Re: breaking sorted material into subsections

For interest, this does not appear to work in Oracle XSLT 2.0.2.8 or 2.0.2.9.
Having played around with a similar variation on this solution the problem seems
to be when the expression in the 'use' attribute of the key declaration
references a function, i.e. it is OK if a simple element or attribute reference
is used. As soon as the key is referenced in the template an 'XSL-1036 : Cannot
convert string to node set' message is given. A shame, as this method allows the
'index' to be built without concern to the source data order. Is there another
way ?
