Re: [dom] Clarify what Document constructor does? (#137)

Because, due to HTM5, we can use SVG and MathML in X(HT)ML and vice versa, so therefore there is no need to maintain separate SVGDocument and MathMLDocument interface. We can leave only Document with some limitation for different commands (if necessary). In theory this should simplify the further development of specifications, but practice will show if browses  will go in this direction. There are other concerns that need to be addressed:

XMLDocument still exist because compatibility reason, although in future it may disappear:
