My proposal and yours are not mutually exclusive.
I am thinking about a useful way to implement input() for a web environment,
such that the xql scripts do not need to use non-standard functions.
xq.setInput(source) looks good for an API. It should probably result in
CallContext.setInput(source).

Wouldn't the document() function do what you need?
