[jdev] bad-request error type

[Sylvain Hellegouarch]

Hi,

Since this is my first message to the XMPP list, forgive me if this is
not the right one.

I am currently implementing XMPP core and its extensions and I ran into
something I wanted to clarify:

RFC 3920 says:

<bad-request/> -- the sender has sent XML that is malformed or that
cannot be processed (e.g., an IQ stanza that includes an unrecognized
value of the 'type' attribute); the associated error type SHOULD be
"modify".

The "modify" value is backed up by XEP 0086. However XEP 0095, section
3.2 Example 7, reads:

 <error code='400' type='cancel'>
    <bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
    <bad-profile xmlns='http://jabber.org/protocol/si'/>
  </error>

Now the SHOULD level defined in RFC 3920 means that there should be a
good reason for XEP0095 not use "modify" in place of "cancel" but I fail
to see such valid reason. Could it just be a mistake? If so is "modify"
valid in that Example?

Thanks,
- Sylvain
