A thing such as the global object isn't available in all languages, whilst
we're only really using javascript in client-side svg the WG can't be
javascript specific in case things change in the future.  I don't think
the WG should talk about global objects at all.  I'd also suggest the
SVGWindow Interface shouldn't be talked of as being global, as you note
it's confusing when embedded in other documents (or how about when the svg
document is a background image defined in CSS from another doc...)

DOM3 L&S doesn't do the same job, for example they don't provide a getURL
or postURL - all they all provide is a load XML from a url and serialise
XML to a url, they're XML specific - getURL/postURL isn't, and very, very
much should not be, provide people with the most general tools they need,
only then start with going more specific.

We definately do not want synchronous downloads in client-side svg -
javascript is single threaded event driven, synchronous downloads are a
_very_ bad idea in such an environment.
