There can be no real answer to the question unless more is known about how
you intend to use the xml and what your data model is. It is as if you
asked for the best table design for a relational database.
What can be said is that
a) is like uncommented code - too obscure if people are supposed to work
with it or write it by hand,
b) Here you are treating the group url as if it were a separate row in a
table. Instead, it is a property of the group, or otherwise it could just
be added to each url. You could add a "baseurl" attribute to the containing
element for each group to hold it.
c) uses xml:base incorrectly - it is used for readjusting the expansion of
relative urls, and you rae not using it that way.
