See my proposal in the thread “an idea: ports == options”.

The req isn’t saying either that XDM is not an option. I think XDM should be carefully considered.

Saying that data flowing through a pipeline is xs:hexBinary or xs:base64Binary does not mean that the data *MUST* be serialized until it’s explicitly asked (as a string or document node). Implementations could very well use a stream handle underneath.

Another option is the “resource manager” approach, where you could represent non-XML content by reference (URI). Again, this can be compatible with an XDM approach.

I don’t really buy the “then use XQuery” argument.
