Strip common prefix from the declaration's name.
Keep a list of root nodes, such that children whos parent
scopes are not accepted but which themselfs are correct can
be maintained as new root nodes.
test whether the declaration matches one of the prefixes, strip
it off, and return success. Success means that the declaration matches
the prefix set and thus should not be removed from the ASG.
