That's understood. But what confuses me is the relation to XHR2 -- it 
seems that this WG is splitting time for work on two specs, where just 
working on XHR2 would be more useful.

Pointer, please?

Are you referring to: "14. If the user argument was not omitted and is 
not null let stored user be user  encoded using the encoding specified 
in the relevant authentication scheme or UTF-8 if the scheme fails to 
specify an encoding."?

This has two problems:

- it makes "stored used" an octet sequence, not a string.

- it simply doesn't work in practice, for instance for Basic Authentication

Well, we continue to disagree on this point.

The goal for examples should be to illustrate a specific feature, not to 
promote a specific coding practice (at least not when doing the latter 
affects the readability).
