[Users] SIP general question about via header

[Ricardo Martinez]

Hello
	Is permitted to mix the two via forms (normal form and compact form) in one SIP message?

For example i have an INVITE with this VIA's : 

INVITE sip:005623341876 at 10.0.0.67:5060 SIP/2.0
Record-Route: <sip:10.0.0.36;ftag=2179110362;lr=on>
Record-Route: <sip:10.0.0.35;ftag=2179110362;lr=on>
Via: SIP/2.0/UDP 10.0.0.36;branch=z9hG4bK58f4.cdc602d2.0
Via: SIP/2.0/UDP 10.0.0.35;branch=z9hG4bK58f4.83fe5745.0
v: SIP/2.0/UDP 64.76.148.234:5060;branch=z9hG4bK2881566366

....

If the answer is yes where can i found some documents to support this information?
Thanks again!

Best Regards,

Ricardo Martinez.-
