Continuing my work parsing through Table Type Patterns and fitting rules into the described pipelines. In the last week I've refactored the code into more of a library and my script which prints tables uses much of the same code as that fitting rules.

I've also looked at parsing some of the sample Table Type Patterns provided by the working group. These include more complexity when describing matches compare with the ofdpa TTP, most notably they use meta_members within matches and flows. Meta_members add constraints such as "one_or_more", "exactly_one" these can also be nested (by default "all" is used). As expected there are a couple of special cases I've had to handle to make these TTPs work, things which are human interpretable but not easily machine readable. Or cases where the use of fields are used in an inconsistent manner, partly due to vagueness in some parts of the spec.
