Not alone, you have to use <xsl:expr> to evaluate a logic expression.
for example

 <xsp:element name="contender">

suppose you have java as your logic, you would get


after execution of "contender.xml?contender-name=Prada". A stupid
example, but shows my point.

Yes. You'd have to transform that tag into some XSP tags that include
the logic for database access or use the database taglibs (that will be
provided in the future)

Well this is up to you... you should do something like

 <xsp:element name="a">
  <xsp:attribute name="href">data.xml</xsp:attribute>
  <xsp:attribute name="contender">

see above.

BTW, forward XSP questions to the Cocoon mail lists next time.
