  I have another two question:
1. According to the roadmap, you will research the “HTML-only wiki support” and “DOM-based templating”. Does it mean that if you launch these functions, wikitext will no longer be supported, even the round-trip doesn’t work? 

At least initially, HTML-only wiki support will mean that it is *possible* to install an HTML-only wiki, not that it is required.

DOM-based templating is an orthogonal issue; long-term we are trying to make template nesting more sane.

2. In “MediaWiki_DOM_spec” there are a lot of discussing and implemented status. Will the parsoid output change a lot in the future?  What is the approximate percentage?

Sections which are not explicitly marked w/ discussion or 'implementing' are expected to remain stable.  We reserve the right to change the spec if needed, but most of it is in production use and working satisfactorily and is not expected to change.  The most in-flux bits are the bits which are not currently implemented and/or supported by Visual Editor.  Our process is to work out a spec proposal with the Visual Editor team, implement it in Parsoid, then implement support for the new feature in Visual Editor.  During these stages the spec is often found deficient in some way and is fixed.  Once the feature lands in Visual Editor and is deployed, we have reasonable confidence that the spec is correct and will not need to be changed further.
