According to XSLT 1.0 specificatoion (
http://www.w3.org/TR/1999/REC-xslt-19991116 ), xsl:key is a
top-level element. Therefore you cannot place it outside a
xsl:stylesheet/xsl:transform .
The easiest solution: do not use keys. Keys are a mechanism to optimize
performance; their
functionality can be obtained by XPath expressions.
The second way to solve your problem: find a way to declare them globally.
Generally speaking,
this is application dependent, and without providing at least the context in
which your key must
be computed (the matched pattern by your template), it is impossible to say
which would that be.
In particular, I find that your variable "projectSum" and your key
"countDetail" does not depend
in any way of context node, therefore I think that just by moving them in the
document element of
your template (xsl:stylesheet/xsl:transform), making them top-level elements,
you will get your
desired functionality.

I am creating a key inside a template with RTF as
below:
<xsl:variable name="projectSum">
<xsl:for-each select="//project">
<xsl:variable name="projectname" select="./@name"/>
<xsl:variable name="projectid" select="@id"/>
<xsl:variable name="projectref"
select="projectelement/@ref"/>
<xsl:copy>
<xsl:copy-of select="./@name"/>
<xsl:copy-of select="./@id"/>
<projectsum>
<xsl:copy-of
select="count(key('ProjectPartNumber',$projectref))"/>
</projectsum>
</xsl:copy>
</xsl:for-each>
</xsl:variable>
<xsl:key name="countDetail"
match="exslt:node-set($projectSum)/projectsum"
use="./@id"/>
In XALAN it throws error with message "Incorrect place
of defining Key".
I am not sure whether it is possible to create a key
with RTF within a template?
If not possible, is there any otherway to achive the
same functionality?

Ranjan
