Hi Norman and Graydon,
This was indeed the issue. I added as="attribute()" to the function parameter
and variable inside the function, and it works perfectly!
Many thanks,
- Chris

Try <xsl:function name="mine:recopy" as="attribute()*">
I think what’s happening is that, because your function doesn’t declare its
return type, what it’s returning is wrapped in a document node and you can’t do
that with attributes.

I'm trying to pass attribute nodes from an element template to a
function, make a modified copy of the attributes inside the function,
then return them for inclusion in the element. But when I attempt
this, I get
Cannot create an attribute node (class) whose parent is a document node.
You put the attributes in a variable:
<xsl:variable name="new_atts">
<xsl:sequence select="$orig_atts"/>
</xsl:variable>
By default, any untyped variable will be created as a document node.
You avoid that by using "as" to specify a type, specifically that this variable
is a sequence of one or more attributes:
<xsl:variable name="new_atts" as="attribute()+">
<xsl:sequence select="$orig_atts"/>
</xsl:variable>
(Possibly zero or more, which would make it "attribute()*".
