[plt-scheme] [ANN] Scheme API to Sedna XML database system

Hi,

the Scheme API to the Sedna XML Database system and its PLT-compatible
implementation is now avaliable as part of the Sedna distribution.

Visit the Sedna home page at
http://www.modis.ispras.ru/Development/sedna.htm

Via the API you can execute queries and updates (in XQuery and a declarative
updata language, respectively) and get the result in (1) XML or (2) SXML.
You can find the API specification in
http://www.modis.ispras.ru/Development/Documentation/Sedna/ProgGuide.pdf

Many thanks to Kirill Lisovsky for fruitful discussions concerning the
Scheme API.
