not necessarily.

one way to think of xmlns-based relabeling is that it translates label-sets
(conceived in a two-d plane) from a set of variably located lines specified by
the prefixes to a single constant line specified by the namespace name.

one way to think of attribute-based relabeling is that it translates label
sets from a constant origin line to a set of variably located lines specified
by the attribute values.

the size of the respective sets of labels does not change.
