Hi, I have still a single doubt about URI params and headers, let me explain 
with some cases:


a) RURI = sip:[EMAIL PROTECTED];p1=xxx;p2=yyy

- p1 and p2 are URI params since it's a SIP-URI.
Sure.


b) From: sip:[EMAIL PROTECTED];hp1=xxx;hp2=yyy

- hp1 and hp2 are header params and no URI params since it's a addr-spec.
Sure.


c) From: <sip:[EMAIL PROTECTED];p1=xxx;p2=yyy>

- p1 and p2 are URI params since it's a name-addr and params are into < >. 
Sure.


d) From: <sip:[EMAIL PROTECTED];p1=xxx;p2=yyy?header1=KKK>

- p1 and p2 are URI params since it's a name-addr and params are into < >.
- header1 is a URI header.
Sure.


e) From: <sip:[EMAIL PROTECTED];p1=xxx;p2=yyy?header1=KKK>;hp1=GGG

- p1 and p2 are URI params since it's a name-addr and params are into < >.
- header1 is a URI header.
- hp1 is a header param since it's outside of < >.
Sure.


f) From: sip:[EMAIL PROTECTED];p1=xxx;p2=yyy?header1=KKK

What about this?
Are p1 and p2 URI params or header params? Note that it's the same case as a) 
but adding a URI header.
Also, is this header1 valid?


I think this is the last question I've about ABNF in headers and URI :)

Thanks a lot.
