Constructing new cocatenated element content

Hi.

I would like to represent an element in XML which represents the JDBC 
timestamp format. It slightly differs from xs:dateTime (JDBC timestamp 
is "CCYY-MM-DD hh:mm:ss", but xs:dateTime is "CCYY-MM-DDThh:mm:ss"). I 
thought of concatenating the schema datatypes xs:date and xs:time, 
separated by a blank.
I would appreciate any hint on this. Thx!

Regards.
