XSL Preprocessing: Does Xalan’s document(URI) work?

Hi fellows,

For the first time I have XML source file with xi:include tags, like

<xi:include href="other.xml"/>

Many XSLT processor automatically process the xi:include element, but Xalan-C as shipped with FrameMaker apparently does not. So I added this to my preprocessing stylesheet:

<xsl:template match="xi:include">
   <xsl:apply-templates select="document(@href)/*" />
</xsl:template>

FrameMaker 10 (in this case, hadn't had the time to test with previous version) hangs with 100% processor usage as soon as I access the document() function.

Has anyone successfully used the XSLT document() function with FrameMaker?

Thanks,

- Michael
