No, and complicating your circumstance: RFC6648

Here's the title & abstract:


          Deprecating the "X-" Prefix and Similar Constructs
                       in Application Protocols

Abstract

  Historically, designers and implementers of application protocols
  have often distinguished between standardized and unstandardized
  parameters by prefixing the names of unstandardized parameters with
  the string "X-" or similar constructs.  In practice, that convention
  causes more problems than it solves.  Therefore, this document
  deprecates the convention for newly defined parameters with textual
  (as opposed to numerical) names in application protocols.
