After checking the schema, I have seen some places that the schema  
(specifically basetypes.xsd) is missing things that are indeed  
supported by ADL (namely assumed\_values, lists, etc.)  
What is the process to update the schema?

I suggest you create a candidate and upload it [here](http://www.openehr.org/wiki/display/spec/XML+Schemas) to discuss with others. Once we have a good one that a reasonable number of people agree on, it can go into the live TRUNK of the specifications SVN, with status ‘development’.
