I originally tried it without wrapping it in the data function and
have also tried casting it to string (where I get a different but
similar answer).
I'm sure there is a simple answer out there.
Yes, both the data() function the group-adjacent= attribute are each
expecting a singleton evaluation and you are supplying a sequence
expression that returns more than a singleton value.
The expression is evaluated from the context of the member of the
population being grouped. The expression descendant::*/local-name()
returns a sequence of strings being the local name of all of the
descendant elements of each element of the population. The error
message is quite explicit in what is wrong.
What is it you are trying to do?
I hope this helps.
