Datacage: Introduced <dc:container-context>.
It is an analogon to <dc:context> to fetch the data from a collection.
Usage:
<dc:container-context container="myContainer">
<dc:properties>
<dc:property name="a"/>
<dc:property name="b" alias="c"/>
</dc:properties>
<dc:for-each><!-- as usual --></dc:for-each>
</dc:container-context>
Iterates over the collection stored on stack with the name 'myContainer'
and fetched for each item via getA() and getB() the values to be stored
under 'a' and 'c'. dc:has-result() & Co work as expected.
