DOMID_SELF is a magic number used as a placeholder to mean "this
domain", it is interpreted this way by various routines in the
hypervsor, it is not literally the domid of the current domain.

I suggest you grep the Xen source for the definition and use of
DOMID_SELF, all should become clear.

In general domains are not (and do not need to be) aware of their own
domain id.
