I’d like to re-launch the work on core data types. Please,
see issue ticket for some background discussion http://www.fpml.org/issues/view.php?id=313
My opinion in terms of principles for this:
- Enforcement should be done at
the schema level, not as guideline.
- People pay less attention to
guidelines than schema definitions.
- Benefits of schema
implementation are not available in a guideline document.
- Data types should bring value
to the grammar. Data types that don’t bring any value to existing
types or to existing xsd simple types should not be incorporated.
- i.e. What’s the value of
a new type that is equivalent to an existing xsd type?
- i.e. There is value in having
a common data type for all schemes. Inconsistency between them is a
problem currently.
- Convergence with other
standards is good and necessary but only when types bring value to the
grammar and don’t confuse existing users.
- The distinction between basis
points and percentage would introduce confusion to FpML.
- What’s the value of having
a generic Numeric data type?
Opinions on this are very welcome.
I’ll send a separate e-mail with my suggested changes
to the current proposal.
Kind Regards,
-Marc
