<p class='phone'><cite>Raphael:</cite> the related problem

deals with extensibility<br />
|

... of the URI syntax</p>
|
|

<p class='phone'><cite>Philip:</cite> the whole thing is to

have a break into name/value pairs<br />

|
... and then be relaxed if you don't understand all name/value

pairs<br />
|
|
... I think we should have a syntax, that mandates what we

should have as name/value<br />

... parsers fail for typos<br />

<p class='phone'><cite>Yves:</cite> what bothers me that the

ABNF tells both what the syntax is and how to parse it<br />
|

be recognized as a Media Fragment</p>

<p class='irc'><<cite>foolip</cite>> "parsers fail for

typos" isn't correct</p>

|
|
|

<p class='phone'><cite>Yves:</cite> we could put an algorithm

|
for the browser<br />
|
|
... we need to decide first what to do with extensibility<br />
|
|
... then I don't see problem of having the algo closed to the
|
|
ABNF definition<br />
|
|
... so Annex D will move up towards the formal grammar</p>
|

<p class='phone'><cite>Erik:</cite> I will not make the parsing

whole URI before, then parsers will be broken with version

2</p>
