Getting to your actual question...

The "negative testing" comment refers to the fact that these fields
are only relevant at the binary packet level.

LTK Perl will build messages with whatever value is provided if these
fields are included. So if you told it to build a <ADD_ROSPEC> message
you could alter the TypeID, or put a abitrary value in the Reserved or
even change the Length to a bogus value.

So for testing readers we actually do use them, and LTK Perl
implements them. But a production client app would never use them.
