   According to one site, <http://www.topxml.com/xsl/elmxsl_attribute.asp>, 
the xsl:attribute element may be contained within a xsl:when element, so 
your stylesheet is technically valid.  But, I believe you're using a 
loophole in that it really must be used within a xsl:element 
element.  Here's a quote from the site:

Element:xsl:attribute
Generates an attribute in the destination document. It should be used in 
the context of an element (either a literal, xsl:element or some other 
element that generates an element in the output). It must occur before any 
text or element content is generated.

   As a minimum-effort suggestion, I recommend modifying your variable to 
be like this:
<xsl:variable name='y'>
   <xsl:element name="'something'">
     <xsl:call-template name='attributes'/>
   </xsl:element>
</xsl:variable>

although I suspect a more hefty re-work may be necessary.  Your variable 
will probably not be a true node, so will have to be converted to a 
node-set using an extension function.  After this conversion, you'll likely 
want the first child of the new set.
<xsl:variable "y2" select="msxsl:node-set($y)"/>
<xsl:variable "y3" select="$y2/*[1]"/>
