[ANN] Sedna Scheme API with SXML support

Hi,

we are pleased to announce that
1) the Sedna XML database system v0.2 provides representation of query
results in SXML
2) support for Scheme API allows quering and updating XML data from a Scheme
program

In the Scheme API, the results of queries are processed in lazy manner that
allows dealing with big amounts of XML/SXML data from Scheme.

The Sedna distribution includes the API implementations for PLT and Chicken.

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