I'm not sure this is true as RFC 2396 section 5.2 step 2) is as follows:
"""

   2) If the path component is empty and the scheme, authority, and
      query components are undefined, then it is a reference to the
      current document and we are done.  Otherwise, the reference URI's
      query and fragment components are defined as found (or not found)
      within the URI reference and not inherited from the base URI.

"""

The first sentence is true for a relative uri reference such as #bare-name.
And the reverse of the second sentence implies either that the 
"a.file" bit has an effect.

An alternative interpretation is that #bare-name = ""+#bare-name and does not 
inherit anything at all from xml:base, which is not very reasonable from my point of view.

best regards
Konrad
