/* ippTag::getTagString ****************************************************

For command tags, this allows tags in the range [1, 99999]. For
event tags, this allows [E0000, E9999]. These are the ranges provided
in the spec, pages 35 and 36. If a tag is out of range, buffer is
set to NULL.

The buffer must be at least TAGSTRINGSIZE (6) characters long.

Since the _tagNumber is an unsigned int, it does not need to be tested
for being positive.
