[xsl] Contexts that are atomic values

[Michel Charpentier <charpov@xxxxxxx>]

Hi,

I need to organize a list of items by genre (@type) so that all the  
items of a given genre end up in the same file.  The following code  
works:

    <xsl:template match="items">
        <xsl:for-each select="distinct-values(item/@type)">
            <xsl:result-document href="html/{.}.html">
                <xsl:apply-templates select="document('music.xml')/ 
key('by-type',current())"/>
            </xsl:result-document>
        </xsl:for-each>
    </xsl:template>

What bothers me is that I need the 'document("music.xml")' part  
('music.xml' is the xml file I'm processing).  If I don't have it,  
Saxon (8B) complains that it cannot process nodes from an atomic  
context (the string I'm currently processing, I suppose).  Same thing  
if I use //item[@type = current()] instead of a call to key().  So,  
whether I use key() or not, I still need to start from 'document 
("music.xml")' and I don't like it.

Is this behavior normal?  Is there a workaround that does not require  
me to refer to 'music.xml' explicitly?

Thanks,

MC
