No, i mean will it ever get serialized as a namespace attribute?

Probably not.
I think i have a way around the solution. The JAXB prefixIndex can be
used to access an array that contains both the FI prefix and namespace
URI index. Thus there is still the same cost for namespace declarations
(which are rare) but the lookup is fast for literal names (which is more
common).

OK. I think i may be able to avoid depending on this assumption now.
