I have two elements that differ only by attribute. My for-each-group

enough about XPath yet to construct a proper current-grouping-key().
(I'm reading Michael Kay's 4th edition, but have not covered the XPath
section yet). Everything I have tried with | @* has failed.
The two elements that need to be distinguished are:
<Heading entry="author">Hahn, Henry</Heading>
<Heading entry="subject">Hahn, Henry</Heading>
The code snippet is:
<xsl:for-each-group select="Item" group-by="Heading"
collation="{$sorting-collation}">
<xsl:sort select="current-grouping-key()"
collation="{$sorting-collation}"/>
I am not sure I understand what you want to achieve.
If you want group by the Heading elements which have an attribute
entry="author" then you can do that with
<xsl:for-each-group select="Item" group-by="Heading[(_at_)entry = 'author']">
