Re: [whatwg] URL resolution of fragment urls in html5 webapps

Holly cow! IE8 and 9 (but not 10) actually resolve the in-document urls
just as I want even with base[href] set.

Could that be used as an argument for clarifying the spec on url resolution
and making the in-document navigation with base set possible?

btw Alex, I looked at the Navigation Controller and it would definitely
help if the in-document navigation was something that I could control with
it. But ideally, I shouldn't need to do anything for the in-document
navigation to work.
