Regarding handling URI fragments, section 3.1 [0] of the 07 draft states in point 4 that 

    4.   If /uri/ has a <fragment> component, then fail this algorithm.

However, the "XMLHttpRequest, W3C Candidate Recommendation 3 August 2010" specification states that the caller is supposed to DROP the fragment (i.e. to ignore, not to fail): 

    1. Let url be a URL. 
    2. Let URL character encoding of url be UTF-8. 
    3. Resolve url relative to the XMLHttpRequest base URL. If the algorithm returns an error raise a SYNTAX_ERR exception and terminate these steps. 
    4. Drop <fragment> from url. 

This is also the correct behavior for HTTP clients and consistent with URI semantics. 

I propose that the text be changed to the following:

    4.   If /uri/ has a <fragment> component, then drop it.

Thanks,

Henrik
