Yeah, I hear you.

Yes, I think that's a possibility. Only time will tell.

I was surprised when consensus in the WG formed around string values
only, especially for parameters which both XSLT and XQuery allow to
have node values.

Courtesty of a long train ride home last night, I've actually
implemented an extension in XProc which allows any XDM value as the
value of an option, parameter, or variable.

I'm not sure this is a good idea, but I thought it would be an
interesting exercise.
