Re: Pick up generated numbering for cross reference us

It can be calculated I think. I had great dificulty writing:

'Count the number of tables in the current section only, before the 
table with <table id="csrh026a.dia-6"> , and add 1', from within the 
xref xslt declaration. Should that be something like:

<xsl:value-of select="count(preceding::table[@id='$linkend'])+1" />
or
<xsl:value-of 
select="count(parent::section//table[@id='$linkend']/preceding::table[@id='$linkend'])+1" 
/>

condensed XML source:

<procedure>
    <section>
       <step><table id="1234-3"><!--lines removed--></table></step>
       <step><step><table id="1234-1"><!--lines 
removed--></table></step></step>
    </section>
    <section>
       <table id="1234-2"><!--lines removed--></table></step>
       <step><ptxt>Refer to <xref role="table" linkend="1234-1"/> for 
more info.</ptxt></step>
    </section>
<procedure>

should return:
... Refer to table 1.2 for more info. ...

>>The XML code for origin and target of the link:

>>	<table id="csrh026a.dia-6">

>>			<xsl:variable name="linkend" select="."/>

>>						</xsl:when>
>>					</xsl:choose>
>>				</xsl:for-each>
>>			</xsl:element>
>>		</xsl:for-each>
>>	</xsl:template>
>>
>>The "x.x" should be the number of the table where I refer too.

>>Questions:
