RE: [Sip] ABNF issue

The answer to this question:

> the header name token always be at the beginning of a new line.

is:

	RFC-3261 does not specifically ALLOW the name token to be proceeded by LWS, i.e. the definition of message-header per ABNF is:

	message-header = (Accept / .... / extension-header) CRLF

Therefore, the header name token MUST always be at the beginning of a new line.
