No, fragments have nothing to do with the definition of schemes.
They occasionally have something to do with how schemes are used,
such as

   mailto:ted.ietf@gmail.com#subject

could be used, for example, to refer to either the owner of that mailbox
or to opening an email entry form with "ted.ietf@gmail.com" pre-filled
in the To field and the active cursor placed in an input field named
subject.  We don't know its true definition, if any, until someone
builds a system that happens to use the identifier in that fashion.
