I wanted to use antfetch with propertyset nested element.
Antfetch was just a copy of ant task from ant 1.5 with
a few lines added to handle returnName property and
propertyset is only available from ant 1.6.
I updated antfetch so that it is now based on ant task
from ant 1.6.5 and propertyset and some other news
properties and nested elements are now supported.
