1- implement counted transitions at the automata level 2 3- Unicode: 4 + upgrade to 3.2 5 + improve the python script to generate better test 6 expressions to check the list of ranges. 7 8- Implement the interface at the SAX level 9 10- Implement the missing parts in the Structure part 11 + all content model 12 + enumerations 13 + countless others c.f. the TODO scattered in the code 14 15- Complete the Built-In datatype collections and Facets implementations 16 17- Regression tests based on 18 + the primer: 19 http://www.w3.org/TR/xmlschema-0/ 20 + the Schemas Test Collection: 21 http://www.w3.org/2001/05/xmlschema-test-collection/ 22 + archives of the schemas-dev list 23 24- Integrity constraints: 25 + what's that ? How need to read about it 26 27- "formal" checking, i.e. go through the full Structure spec and 28 bind code and associated parts of the Schemas spec 29 30- go though the erratas 31 http://www.w3.org/2001/05/xmlschema-errata 32
