-Structured target profiles -- Zeerex? -- requires libxml
-Normalization of records -- test if libXSLT is fast enough to:
- -- Extract Subject headings, titles, dates, authors for facets and display
- -- Merge keys for relevance ranking, etc.
- -- Also normalize to UTF-8.
-Factor Z39.50 stuff out from pazpar2.c to separate file to make room for
- later SRU implementation.
-Sort by title, date, author. Parameter to 'show' webservice command.
-Additional facets. At least do 'author'.. think about making it general. -- libxml
-Support for 'blocking' requests, at least for record display before first records
- are retrieved (to reduce polling).
-Implement detection of 'search complete', so client knows when to stop polling.
-Full record retrieval. -- libxml
-Implement hitsbytarget function to emulate traditional LOT-style U/I
