At the moment, we only have DOM reference docs for HTML in the Studio's internal help pages.
We need proper HTML help docs that provides better explanations and samples.
- Convert existing XSL from Studio 2.X to work against new HTML metadata format. Likely requires some, but not a huge amount, of tweaks.
- Add HTML document generation to build process, similar to JS docs.
