x1 is a sign language of x2
Replacement for ableist term xanbau, which appears to be based on misconceptions about signing and Deaf culture. Sign language is not "hand language". Any speaker of sign language can tell you that signing involves not just the hands, but the whole body: face, chest, lips, posture, facial expression/body language, lip movement, and so forth. Therefore, "corci" (gesture) makes a far better modifying component for this lujvo.
