This would produce intermixed CVE and linux-git lines unless the tags
are sorted correctly in the source code, I do not want to depend on the
order hence the two loops.

I've tried to explain to pvorel already that this is a wrong place to
assert the tag names. If nothing else this piece of code will be rarely
triggered and the error would end up ignored.

I plan to assert the tag names in the docparse tool that will build the
test metadata during the LTP build, so that wrong metadata will actually
fail the LTP build.
