There is indeed no requirement in HTML5 that an HTML5 UA implement SVG and 
MathML (though there are requirements that they be parsed correctly).

I've tried to minimise the required dependencies. Really the only required 
dependencies are ARIA, Unicode, and IRIs. Other than that, I don't think 
there's really any requirement. For example, all the XML support is 
optional, CSS and HTTP are optional, all the scripting and DOM stuff is 
optional, things like Media Queries are only required if you support 
things that make it relevant (e.g. a video format or CSS), and so on.
