Thank you David for the most precise explanation.. I
have another related doubt..
Supposing, I want to apply key() function within the
below for-each loop, on the document constructed from
the source XML(and not the RTF)
<xsl:for-each
select="exsl:node-set($rtf)/someelement">
<!-- using key() here to operate on the document
representing the source XML; not the RTF -->
</xsl:for-each>
Can this be done..?
I feel, this could be a requirement in applications..
Regards,
Mukul

But please consider this.., if for instance, the
main
XML document also contained the <projectsum>
nodes,
then the key definition -
<xsl:key name="countDetail" match="projectsum"
use="@id"/>
would include those nodes also in the scope.. So
introducing the <temp> tag would be neccessary to
enforce the scope to RTF..
No, XSLT indexes each document _separately_ key()
only ever returns
nodes from one document (the document which the
current node is in).
So if the current node is in a document which
resulted from calling
xx:node-set on an rtf, any use of key will only
return nodes from that
same document, there is no other scoping required
(or possible).
In this case even if other documents (such as the
main input document)
contain projectsum elements they will not be
returned by key() because
no nodes from other documents are ever returned.
