My work on HTML Tidy was motivated by an attempt to deal with this
by providing an Open Source solution for converting Tag Soup
documents into something easier to process.

One problem in writing a formal spec for tag soup is that there
are significant differences between Navigator and IE. Microsoft's
reverse engineering team got it close, but not close enough. In any
event, few people have expressed a common need for such a spec.
Discussions over time in the various HTML working groups have tended
to be prescriptive, focussing on how people should write rather that
what they do write in practice. Browser implementers are required to
take a more pragmatic view though, and the existing specs are just
the tip of the iceberg.

As we move forward, I am hoping that the specs and what you need
to implement in products will get progressively closer together,
which will make it easier to ensure full interoperability.
