> I'd like to see the SQLTransformer add some meaningful markup to arrays. 
> If i have understood it correctly, arrays are part of SQL3, and has been
> implemented in JDBC, see
> http://java.sun.com/j2se/1.3/docs/guide/jdbc/getstart/mapping.html#1037699
> Some database vendors, for example PostgreSQL have their own Array
> implementation. While it isn't quite clear from the PostgreSQL docs how their
> JDBC-driver handles this, it seems to be mapping to the Java Array type. 
> I have experimented with the PostgreSQL Arrays, and the serialized XML looks
> like this:
> <rowset
> xmlns="http://apache.org/cocoon/SQL/2.0"><row><fid>1</fid><navn>Test11</navn><arr>{Testerarr,merarray}</arr></row>
> ...
> the stuff enclosed in curly brackets is an array. 
> It would have been nice if this had been broken up, for example like this:
> <rowset xmlns="http://apache.org/cocoon/SQL/2.1">
> <row>
> <fid>1</fid>
> <navn>Test11</navn>
> <arr>
> <array-element>Testerarr</array-element>
> <array-element>merarray</array-element>
> </arr>
> </row>...
