Can you clarify how 'parallel' the development of HTML5 and XHTML5 is?
Are they developed in step or is there a lag between one spec being
updated?
They're in the same spec, so they're developed at the same time. HTML
and XHTML aren't really separate languages, but rather different
syntaxes for the same language.
HTML5 is being defined in terms of the DOM, rather than the syntax. So
that both HTML and XHTML share the same elements and semantics, and in
most cases, either serialisation can be used to represent the same
document. Although there are some exceptions caused by the different
parsing requirements. e.g. <noscript> can only be used in HTML, not in
XHTML; other namespaces (xmlns="") can be used in XHTML, but not in
HTML, etc.
