However, I really need sequences of sequences.
What's the best way to implement sequences of sequences in XSLT 2.0?
xpath 2.1 draft proposes function items, which makes it easy to have a
sequence of references to sequences, but as you say in xpath 2 it isn't
supported by the data model.
Has anyone already implemented some XSLT functions that provide sequences of
sequences?
You can't easily implement functions that use a datatype that doesn't exist.
options are
1) wait for 2.1
or
2) use a single sequence, using marker items (or fixed length) to denote
where the subsequences stop and finish.
or
3
serialise the sequences to an xml structure and then use xml tree
nesting to model sequences of sequences.
