I'd like to rough out targets for content for the next several spec drafts:

vNext - (I hope to get this all in this week)
- binary/opaque types resolved - also anySimpleType
- facets discussion integrated in
- choiceType enum and length props on choice
- prefix lengths
- wildcards with dimension fix
- xs:integer type added

vX+1
- 2-level description (schema components)
- nulls/default/optionals
- regular expressions for lengths
- expression language
- valueCalc

vX+2
- assertions/discriminators and choice
- how speculative parsing works
- reordering properties discussion (move representation earlier)

vX+3
- escapeSchemes
- string xml type
- variables and selectors
- improvments on property descriptions
