include chunk of xsl - xslt

Question

I have a chunk of XSL code (along with Apache fop), that i want to reuse:
XSL version and schema used
<xsl:stylesheet version="3.0" xml:lang="en"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:exsl="http://exslt.org/common"
xmlns:java="http://xml.apache.org/xslt/java"
exclude-result-prefixes="java"
xmlns:map="xalan://java.util.HashMap" extension-element-prefixes="map">
Chunk to reuse:
<xsl:choose>
<xsl:when test="map:get($etiquetas,'datosMensajeLabel')" />
<fo:table-cell padding="2pt" border-top-color="black"
border-top-width="0.5pt" border-top-style="solid"
background-color="grey">
<fo:block text-align="start" color="white" font-size="12pt">
<xsl:value-of
select="map:put($etiquetas,'datosMensajeLabel','')" />
<xsl:value-of
select="map:get($etiquetas,'datosMensajeLabel')" />
</fo:block>
</fo:table-cell>
</xsl:choose>
<xsl:otherwhise>
<fo:table-cell padding="2pt" background-color="grey">
<fo:block text-align="start" color="white" font-size="12pt">
<xsl:value-of
select="map:get($etiquetas,'datosMensajeLabel')" />
</fo:block>
</fo:table-cell>
</xsl:otherwhise>
I tried so far:
Declare and use named templates: it fails since table-cell breaks the Apache fop schema where template is declared
Put that chunk of code in another file and use import or include: it's of no use as it's not used as a child of xsl:stylesheet

Answer 1

The reason you are getting the error fo:table-cell not allowed in that position is that the preceding xsl:when element is closed and therefore not wrapping the <fo:table-cell> element.
xsl:choose only allows either xsl:when or xsl:otherwise as direct children and thus complains when it finds <fo:table-cell>.
Wrapping xsl:when around <fo:table-cell> should eliminate the error message.
By the way, you have misspelt xsl:otherwise
