Section numbering using xmerl:export

[Mikael Karlsson]

Hmm,
This sounds interesting,
would this also mean that one could perform XSL-type operations like
having an arbitrary order of rearranging/filtering the transformed 
elements, like making a contents table, etc. As it is now it seems that 
you have to maintain the input XML document order in the export.
