3.8 Consider using XDM everywhere

[ndw]

In addition to supporting [XDM] values in variables, options, and parameters, XProc 2.0 might allow [XDM] values in more places, such as allowing p:for-each to iterate over a sequence of strings or integers.

I think that a step can now produce a document that contains a sequence of atomic values. Iterating over that sequence would produce a document for each atomic value and provide those "documents" to the processing pipeline inside p:for-each. Maybe that's close enough to "solved".

We should test this when, you know, we have an implementation :-)

What would be the content type of a sequence of xs:integers?
