- Define l10n.ent as an entity in localized directories and make them be

picked up via XML catalog in freebsd50.ent or xhtml10-freebsd.dtd,
  not entities.ent.  The L10N entities always come first to be able to
  override everything.

- Define   as   in EUC-JP encoding.  This is a workaround to
  prevent an invalid character in EUC-JP caused by converting 0xa0 in
  UTF-8 (EUC-JP does not allow 0xa0) in XSLT processing.  Theoretically
  it should be   still in the final XML output.

- Make XML catalog resolution consistent for l10n.ent.  This should be
  revisited for the others later.
