Sorry if another version of this appears without the stylesheet. I expected 
this stylesheet to work just the way the example shown in the spec does, but 
the comma appears after all instances of <in>. Can anyone see what I'm 
missing?

Your input document is:

<signature>signature <identifier>DNSQuery</identifier>
   <in>in<long>long</long><identifier>a</identifier></in>
   <in>in<string>string</string><identifier>b</identifier></in>
   <in>in<float>float</float><identifier>c</identifier></in>
</signature>

I suppose you are expecting position() to be 1, 2, or 3, and last() to
be 3.  But they're not.  You have text nodes (both empty and non-empty)
within your <signature> element.

For your document,  position() is 4, 6, and 8, and last() is 9.
