Todo for xml interface 'ConTeXtXML' extension:
* add CDATA support for the content of <context>, <xmlcode>, <texcode>, <pre> and <nowiki> .
* (maybe) add a dedicated editing page with split fields
* document the new stuff (ref pages, variants)
* combine the current 'context' extension with the new 'ConTeXtXML' extension
* implement merging with new interface xml releases
