Can we pre-populate the context with namespaces, for example,
controlled via an extension of yang library? Perhaps we can simply
pre-polutate contexts with all module names? Yes, I know this makes
xpath expressions rather verbose but on the other hand it takes away
guesswork and (client) tools may do expansion of an unprefixed
expression into a proper namespace prefixed expression.
