Subject: How strictly is the SIP grammar being followed ?

Hi,
Please refer to definition of a tag-param

tag-param= "tag=" UUID
UUID = 1*(hex|'-')

However, in one of the test messages of 2nd bakeoff (test1.txt) , there was
a
test which had a

tag=12231423424n
and
tag=98ashd<something>

None of the above confirm to the grammar specified, so why should a parser
allow it ?

Just wondering how strictly the tests are following the grammar - if not,
why define a fixed rule set in the first place ?
