Convert schema-aware stylesheet - xslt

Question

I have a schema-aware XSLT transformation that works well. However, the anticipated users of the XSLT will likely not have access to a schema-aware processor. Thus, I'd like to write some code that will convert my schema-aware XSLT into an XSLT that can be used by basic level conforming processors.
For my purposes, the use of schema-aware constructs is limited to matching templates, i.e.
<xsl:template match="element(*, Candidate)">...</>
I'm not expecting this to be a fully automatic process. What I would like is to generate an XSLT that would, for every complexType in an XSD, find its use in a specified surfaced XSD element.
Example code:
<xsd:schema xmlns="example.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="example.xsd" elementFormDefault="qualified" version="0.0">
<xsd:element name="Candidate" type="Candidate"/>
<xsd:complexType name="Candidate">
<xsd:sequence>
<xsd:element name="Code" type="Code" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element name="Name" type="xsd:string" minOccurs="0"/>
<xsd:element name="PartyId" type="Code" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Code">
<xsd:sequence>
<xsd:element name="Value" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
The expected output for the element Candidate would be something like this:
<complexType_usages>
<usage complexType="Code" path="Candidate/Code" />
<usage complexType="Code" path="Candidate/Party" />
</complexType_usages>

Answer 1

It might be simplest to work from a validated instance rather than trying to analyse the schema (so long as the instance is sufficiently representative). For every element, output the type annotation (using saxon:type-annotation) and the path, then take the list of type/path pairs, and eliminate duplicates and redundancy.
