Re: [selectors-api] SVG WG Review of Selectors API

Maybe it was already proposed, but are there any problem to just add a
new argument to querySelectors and querySelectorsAll, with namespace
I don't mean anything like XPathNSResolver or things like that. I just
mean a ES Object, where enumerable property names are namespace
prefixes, and their values are their URI. Invalid properties (whose
name doesn't match the production for a namespace prefix in Namespaces
in XML or whose value is not an URI) are simply ignored.
That is, for any enumerable property in the new argument, a @namespace
declaration will be implied. No other information will be considered
(such as inherited bindings or @namespace declarations outside), any
prefix not bound at selector resolution will cause a NAMESPACE_ERR.

1) people consider it adequate etc: well, it is easy to do (just
{xhtm: "", svg:
"" }) and poweful
2) don't have security issues: are there any security issues with
namespaces in general?
3) don't have undefined behaviour: as I said, it acts like an implied
sequence of @namespace, whose are fully covered (in good and bad
behaviour) by Namespaces in CSS

Hope you'll put this feature at least in version 2 of Selectors API,
or people will go back to XPath.
