I may be being daft, but I can't see how this could easily build up "or"s -
assuming that these things are "and"ed together -
however if the available task also took a "operation" attribute, the task
could combine the conditions appropriately... Example steeling from Ceki
Gulcu's "Conditional compilation" request:
<available property="case1" operation="and">
<if ...test for JNDI... />
<if ...test for JMS... />
</available>
<available property="case2" operation="or">
<if ...test for JAXP from Sun... />
<if ...test for Xerces... />
</available>
