Re: Muenchian grouping on external XML files

Is there any way I can use keys when calling on external XML files using
the document function?

I am trying to use the Muenchian grouping
technique to list unique content values for an element, but the values
exist in a document that is external to the one I'm processing.

More detail below (apologies for long post):

-----------------XSLT FILE--------------
<xsl:key name="myKeyName" match="document('master_primary.xml')//rs"
use="normalize-space(.)" />

<xsl:template match="divGen">
  <xsl:if test="@id='personIndex'">
    <xsl:for-each
select="document('../../xml/02_master/master_object.xml')//rs[generate-i
d(.)=generate-id(key('myKeyName',
normalize-space(.))[1])][@type='person']">

I can think of other methods, using intermediate XML output, but would
prefer to avoid them if possible.
