Re: Generating numbering for cross-references (LONG)

In a typical research document, an author needs to make many
cross-references.  XML provides ID and IDREF attributes for this
purpose, and lots of DTDs are written to make use of them.
...
You
cannot reach over to the relevant part of the tree (by ID) and
pluck a copy of a number which has not yet been generated.

At the point where a reference is made, what is the XPath expression
you need to generate the number which will be the value which will
eventually get assigned to the target?
...
What I find unbelievable is that no-one has yet done this. It must be
one of the most common requirements in document processing, and
without it, XSLT simply cannot be used to reproduce simple numeric
cross-references like "see Figure 16" or <plug>bibliographic
references like Kay[23]</plug> :-)

What have I missed?

   ...
   <xsl:text>See Construct </xsl:text>
   <xsl:for-each select="id(@idref)">
      <xsl:call-template name="construct-number"/>
   </xsl:for-each>
   ...

At the point of definition:
   ...
   <xsl:text>Construct </xsl:text>
   <xsl:call-template name="construct-number"/>
   ...

   <xsl:template name="construct-number">
     ...
     <xsl:number ...>
   </xsl:template>
