I believe that you've gone up an extra and unnecesary level of
abstraction.  I don't believe that your pattern is any more fundamental
than the pattern already established by the XPointer framework in
creating schemes.  We could, of course, make all of the schemes into
similarly abstract patterns, using a single whatever() scheme and
letting its contents determine how

They do not do the same thing.  You can abstract it to "they all set
context", but they all do so quite differently.  You might note, for
instance, that xmlns-local() doesn't even provide a setting or a value.
And if you want to go all the way, we should likely add xmlns to the
list.  How comfortable are people really going to be with:

pragma(http://www.w3.org/ns/xmlns/, xyz, http://example.com/ns/xyz)

I don't find remembering URIs to be any easier than remembering scheme
names.  I don't typically write code of the form:

function(functionName, value, value)

I'd much prefer to write:

functionName(value, value)

That doesn't justify an extra layer of abstraction.  Schemes are already
a substantial abstraction step up from prior practice.

No.  This goes too far up the abstraction tree with or without URIs.

You're welcome to write one, but I would not plan to use it.
