Presumably the code below is executed with the <MapMD> element as the
context node?

node() means child::node(): your MapMD element has no children.

We haven't been told what the parent of the MapMD element is.

Ouch! The order of attributes is undefined. Selecting all attributes
after the second will give you a random set of attribute nodes back.

You haven't told us anything about the Map element, so it's hard to say
anything more...

No idea what this extension function does...

Your MapMD element doesn't have a child called MapKey...

I give up. Show us your whole source document, your whole stylesheet,
and explain what your extension function does.
