Re: breaking sorted material into subsections

[Nick Browne <NickBrowne@xxxxxxxxxxxxxxx>]

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.
