I'm not sure it's as complete an answer as you want, but you certainly 
can use fragment identifiers in XML.

"The syntax and semantics of fragment identifiers for the XML media
   types defined in this specification are based on the
   [XPointerFramework] W3C Recommendation.  It allows simple names and
   more complex constructions based on named schemes.  When the syntax
   of a fragment identifier part of any URI or Internationalized
   Resource Identifier (IRI) ([RFC3987]) with a retrieved media type
   governed by this specification conforms to the syntax specified in
   [XPointerFramework], conforming applications MUST interpret such
   fragment identifiers as designating whatever is specified by the
   [XPointerFramework] together with any other specifications governing
   the XPointer schemes used in those identifiers that the applications
   support.  Conforming applications MUST support the 'element' scheme
   as defined in [XPointerElement], but need not support other schemes."

Section 6 even mentions the dreaded xml:base:
