We could use something stricter than <text/> so that RNG validation
would reject the same names our code rejects, such as:
<data type='string'>
<param name='pattern'>[a-zA-Z0-9]{0,8}</param>
</data>

This name is misleading; I'd use virStrIsAlnum, to match the <ctype.h>
difference between alpha and alnum.
Bigger problem - I see where you parse the new XML, but not where you
generate it back out when formatting. tests/qemuxml2xmltest.c is a good
place to tweak to make sure we can round trip canonical XML. For that,
I think you need a v3.
