Please stop using the X- prefix! See RFC 6648:

This document generalizes from the experience of the email and SIP
communities by doing the following:

   1.  Deprecates the "X-" convention for newly defined parameters in
       application protocols, including new parameters for established
       protocols.  This change applies even where the "X-" convention
       was only implicit, and not explicitly provided, such as was done
       for email in [RFC822].
