Either way doesn't change the point.  If you have a script written
(using names not vapor-PSVI)
under the assumption that there are no local types (or, at least, 
a known set of local types, the others being global, and the
local type not being a compatible restriction of the global type), then
introducing local types forces you to do some more programming
to fix it.  It is not robust.

The reuse of the element may cause some failure, but it is just
as likely to introduce spurious data.  

Contrast this with adding a new global--per-namespace name.
Your script will already have handled this: either strip or fail, probably.
