There is an <if/> task in ant-contrib that does this:
<if>
<isset property="prop"/>
<then>
<echo>Prop is set</echo>
</then>
</if>

A while back there was a discussion about having a syntax for use in the if and unless attributes of targets.
It has occurred to me that perhaps we just need a task akin to "sequential" that can have a
condition data type as its first "child". This condition would determine whether the further
content of the task would be "executed".
This might look like:
<target name="something">
<conditional>
<condition>
<isset property="a.property.name"/>
</condition>
<copy .../>
...
</conditional>
</target>
This example would be equivalent to using the if attribute, but the full power
of condition could be applied.
In addition, this would allow any sub-part of a target (including the default
target) to be made conditional without resorting to the use of properties.
Have I missed an existing Ant capability, or would this be a worthy enhancement?
