Re: Sorted node set and following-sibling axis

Hi Jay,

Unfortunately, although your solution works for me in Saxon 8B, it fails
in Saxon 6.5.3, Xalan and MSXML 4, giving errors on the theme of "Cannot
convert a result tree fragment to a node-set". It seems that Saxon
supports some such conversion automatically (possibly a side-effect of
XSLT 2 support?), but as my client may switch XSLT processors at any time,
I'm having to stick to standard XSLT 1.0.

Thanks for your suggestion; if I can ever guarantee a supporting
processor, I'll bear it in mind. In the meantime, if you need something
similar to work cross-processor, the approach posted by Joris Gillis works
for me.

Regards,

Nick.
