Container element for CMP & FMP, which can have a stable author-defined ID #140

Rationale: linking external datasets to the OpenMath CDs (short example, detailed background)

Proposed XML encoding, and example

Michael, James, is that enough? I'm not really keen on writing it up as a paper-like document, but I can elaborate the information on that page, if anything should still be unclear.

Suggested action:

1. extend the abstract CD specification accordingly, …
2. … as well as the XML reference encoding
3. adapt the CDs hosted on openmath.org accordingly

Issues to be discussed:

• do we want this explicit grouping of CMPs and FMPs (I think the previous discussion shows that we do)
• how to identify properties: relatively to the CD, or relatively to the symbol?
• what syntax to use for a property's ID? (If we identify them per CD, we could also use Property/**xml**:id, but that would contradict the common OpenMath CD style.)
• in addition to the ID, do we also want to provide a human-readable description?
