Need ODM SDF Syntax to Cover the Extension and Extendability of Properties

In Weave Data Language (WDL), both traits and properties within traits may be extended or derived to the extent that they have been marked as such.

extends
- This is a string or number indicating the name or identifier, respectively, of the property being derived from and extended.
extendable
- This is a Boolean indicating whether or not the property may be further derived from and extended.
