* This interface represents the SIP-If-Match header, as defined by
* RFC3903.
*
* The SIP-If-Match header is used by a client (event state publisher) in
* a PUBLISH request, to update previously published event state. The value is
* obtained from the server in a {@link android.javax.sip.header.SIPETagHeader} in a
* 2xx response to a previous PUBLISH.
*
* Sample syntax:
SIP-If-Match: dx200xyz
*
*
* A server must ignore Headers that it does not understand. A proxy must not
* remove or modify Headers that it does not understand.
