It is necessary to bring the country's selectors sorted by name and get rid of duplicates:
<select>
<option value="http://germany.gr">Germany</option>
<option value="france">France</option>
</select>
That is, if the country meets a few times, in value = specify the id. If once, then specify the link
Description grouped as follows: if a country meets several times
Code:
<div id="france">
<p> Lion</p>
<p>Paris</p>
</div>
If the country meets once - did not write

Answer 1

This transformation:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:key name="kObjByCountry" match="Object" use="Property[#Name='COUNTRY']"/>
<xsl:template match="/">
<xsl:variable name="vCountries" select=
"/*/*/*/data/Object
[generate-id()
= generate-id(key('kObjByCountry', Property[#Name='COUNTRY'])[1])
]"/>
<select>
<xsl:apply-templates select="$vCountries">
<xsl:sort select="Property[#Name='COUNTRY']"/>
</xsl:apply-templates>
</select>
<xsl:apply-templates select="$vCountries" mode="desc">
<xsl:sort select="Property[#Name='COUNTRY']"/>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="Object">
<xsl:variable name="v2nd"
select="key('kObjByCountry', Property[#Name='COUNTRY'])[2]"/>
<option value="{(#Id[$v2nd]|Property[#Name='WWW'])[1]}">
<xsl:value-of select="Property[#Name='COUNTRY']"/>
</option>
</xsl:template>
<xsl:template mode="desc"
match="Object[key('kObjByCountry', Property[#Name='COUNTRY'])[2]]">
<div id="sity_{#Id}">
<xsl:apply-templates select=
"key('kObjByCountry', Property[#Name='COUNTRY'])
/Property[#Name='NAME']">
<xsl:sort/>
</xsl:apply-templates>
</div>
</xsl:template>
<xsl:template match="Property[#Name='NAME']">
<p><xsl:value-of select="."/></p>
</xsl:template>
<xsl:template mode="desc"
match="Object[not(key('kObjByCountry', Property[#Name='COUNTRY'])[2])]"/>
</xsl:stylesheet>
when applied on the provided XML document:
<page>
<elements>
<element name="bids">
<data>
<Object Id="id1">
<Property Name="NAME" Order="0">Paris</Property>
<Property Name="COUNTRY">France</Property>
<Property Name="WWW" >http://france.fr</Property>
</Object>
<Object Id="id1">
<Property Name="NAME" Order="0">Lion</Property>
<Property Name="COUNTRY">France</Property>
<Property Name="WWW" >http://france.fr</Property>
</Object>
<Object Id="id2">
<Property Name="NAME" Order="0">Berlin</Property>
<Property Name="COUNTRY">Germany</Property>
<Property Name="WWW" >http://germany.gr</Property>
</Object>
</data>
</element>
</elements>
</page>
produces the wanted, correct result -- in which the countries/cities are sorted:
<select>
<option value="id1">France</option>
<option value="http://germany.gr">Germany</option>
</select>
<div id="sity_id1">
<p>Lion</p>
<p>Paris</p>
</div>
Explanation:
Proper use of the Muenchian grouping method and AVT s.
Proper use of xsl:sort.

Answer 2

With XSLT 1.0 you can use Muechian grouping to perform grouping respectively to identify and eliminate duplicates; the stylesheet
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes"/>
<xsl:key name="k1" match="data/Object" use="#Id"/>
<xsl:template match="data">
<select>
<xsl:apply-templates select="Object[generate-id() = generate-id(key('k1', #Id)[1])]"/>
</select>
<xsl:apply-templates select="Object[generate-id() = generate-id(key('k1', #Id)[1]) and key('k1', #Id)[2]]" mode="desc"/>
</xsl:template>
<xsl:template match="data/Object[key('k1', #Id)[2]]">
<option value="{#Id}">
<xsl:value-of select="Property[#Name = 'COUNTRY']"/>
</option>
</xsl:template>
<xsl:template match="data/Object[not(key('k1', #Id)[2])]">
<option value="{Property[#Name = 'WWW']}">
<xsl:value-of select="Property[#Name = 'COUNTRY']"/>
</option>
</xsl:template>
<xsl:template match="data/Object" mode="desc">
<div id="city_{#Id}">
<xsl:apply-templates select="key('k1', #Id)/Property[#Name = 'NAME']" mode="desc"/>
</div>
</xsl:template>
<xsl:template match="data/Object/Property" mode="desc">
<p>
<xsl:value-of select="."/>
</p>
</xsl:template>
</xsl:stylesheet>
transforms the input
<page>
<elements>
<element name="bids">
<data>
<Object Id="id1">
<Property Name="NAME" Order="0">Paris</Property>
<Property Name="COUNTRY">France</Property>
<Property Name="WWW" >http://france.fr</Property>
</Object>
<Object Id="id1">
<Property Name="NAME" Order="0">Lion</Property>
<Property Name="COUNTRY">France</Property>
<Property Name="WWW" >http://france.fr</Property>
</Object>
<Object Id="id2">
<Property Name="NAME" Order="0">Berlin</Property>
<Property Name="COUNTRY">Germany</Property>
<Property Name="WWW" >http://germany.gr</Property>
</Object>
</data>
</element>
</elements>
</page>
into
<select>
<option value="id1">France</option>
<option value="http://germany.gr">Germany</option></select><div id="city_id1">
<p>Paris</p>
<p>Lion</p>
</div>
[edit]
Here is an adapted stylesheet that uses a different key to try to implement the changed requirements:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements="*"/>
<xsl:output method="html" indent="yes"/>
<xsl:key name="k1" match="data/Object" use="Property[#Name = 'COUNTRY']"/>
<xsl:template match="data[Object]">
<select>
<xsl:apply-templates select="Object[generate-id() = generate-id(key('k1', Property[#Name = 'COUNTRY'])[1])]"/>
</select>
<xsl:apply-templates select="Object[generate-id() = generate-id(key('k1', Property[#Name = 'COUNTRY'])[1]) and key('k1', Property[#Name = 'COUNTRY'])[2]]" mode="desc"/>
</xsl:template>
<xsl:template match="data/Object[key('k1', Property[#Name = 'COUNTRY'])[2]]">
<option value="{Property[#Name = 'COUNTRY']}">
<xsl:value-of select="Property[#Name = 'COUNTRY']"/>
</option>
</xsl:template>
<xsl:template match="data/Object[not(key('k1', Property[#Name = 'COUNTRY'])[2])]">
<option value="{Property[#Name = 'WWW']}">
<xsl:value-of select="Property[#Name = 'COUNTRY']"/>
</option>
</xsl:template>
<xsl:template match="data/Object" mode="desc">
<div id="{Property[#Name = 'COUNTRY']}">
<xsl:apply-templates select="key('k1', Property[#Name = 'COUNTRY'])" mode="link">
<xsl:sort select="#Name"/>
</xsl:apply-templates>
</div>
</xsl:template>
<xsl:template match="data/Object" mode="link">
<p>
<a href="/index.php?id={#Id}">
<xsl:value-of select="#Name"/>
</a>
</p>
</xsl:template>
</xsl:stylesheet>
When I apply that stylesheet to the input
<?xml version="1.0" encoding="utf-8" ?>
<page>
<elements>
<element>
<data>
<Styles Name="default">
<Style Url="/css.css" Browser="default" Version="default"/>
</Styles>
</data>
</element>
<element type="Digillect.WB.Web.Elements.Site.SiteStructureElement">
<config StartLevel="0" MaxDepth="3" UseItemVisibility="false">
<monikers>
<moniker store="asdasd"/>
</monikers>
</config>
<data ParentPath="/">
</data>
</element>
<element name="bids">
<config>
<Object Id="1b61995a-6e22-4b09-af5f-9a50cdaa7863"/>
<Object Id="baa1d3df-0510-4f68-8a41-1b9b22587134"/>
</config>
<data>
<Object Id="id2" Name="Paris">
<Property Name="COUNTRY">France</Property>
<Property Name="WWW" >http://france.fr</Property>
</Object>
<Object Id="id1" Name="Lion">
<Property Name="COUNTRY">France</Property>
<Property Name="WWW" >http://france.fr</Property>
</Object>
<Object Id="id3" Name="Berlin">
<Property Name="COUNTRY">Germany</Property>
<Property Name="WWW" >http://germany.gr</Property>
</Object>
</data>
</element>
</elements>
</page>
the result is
<select>
<option value="France">France</option>
<option value="http://germany.gr">Germany</option></select><div id="France">
<p>Lion</p>
<p>Paris</p>
</div>
so the option elements are grouped as required (although I couldn't figure out what determines the sort order) and the p elements contain links with the #Id value incorporated.
