Jeni,
I've tried your sample using xalan and it complains.
The code is :
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:variable name="sharedDoc">document('../shared/shared.xml')</xsl:variable>
<xsl:key name="mysetofkeys" match="KEYBASE/KEY" use="@NAME"/>
....
<xsl:template match="KEYREF">
<xsl:variable name="keyrefname" select="@LINKEND" />
<xsl:for-each select="$sharedDoc">
<b><xsl:value-of select="key('mysetofkeys', $keyrefname)/ACRONYM" /></b>
</xsl:for-each>
</xsl:template>
...
</xsl:stylesheet>
And the error is, at runtime transformation :
Any idea ?
Regards,
Pierre

Jeni,
I've tried your sample using xalan and it complains.
The code is :
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:variable name="sharedDoc">document('../shared/shared.xml')</xsl:variable>
<xsl:key name="mysetofkeys" match="KEYBASE/KEY" use="@NAME"/>
....
<xsl:template match="KEYREF">
<xsl:variable name="keyrefname" select="@LINKEND" />
<xsl:for-each select="$sharedDoc">
<b><xsl:value-of select="key('mysetofkeys', $keyrefname)/ACRONYM" /></b>
</xsl:for-each>
</xsl:template>
...
</xsl:stylesheet>
And the error is, at runtime transformation :
============================= Transforming... XPATH: Can not convert #UNKNOWN to a NodeList! Xalan: was not successful. XSLProcessor: done
Any idea ?

Unfortunately, I know from struggling with some fairly recent questions that this doesn't work. You can't use the document() function within the 'match' attribute of xsl:key. Instead, define the key as if the input document was the one with the keys in, at the top level of the stylesheet:
<xsl:key name="mysetofkeys" match="/keybase/key" use="@name" />
Then, when you want to use it, put the key() function within an xsl:for-each that has the document that holds the keys as its 'select' attribute:
<xsl:template match="keyref">
<xsl:variable name="keyrefname" select="@name" />
<xsl:for-each select="document('../shared/shared.xml')">
<b><xsl:value-of select="key('mysetofkeys', $keyrefname)/ACRONYM" /></b>
</xsl:for-each>
</xsl:template>
This is kind of explained in the XSLT Recommendation at http://www.w3.org/TR/xslt#function-key, right at the end of that section.
