If you have an XML configuration with lists and attributes like this:
and if you have a different implementation of the DefaultExpressionEngine which implements the query() methode to check these attributes
than you'll only get the attributes for the first node of the list - the
subsequent nodes don't have any attributes set.
So for "str1" I'll get the attribute environment="test", for "str2"
and "str3" I'll get no attributes.
Oliver H. pointed out that this is the intended behaviour (http://mail-archives.apache.org/mod_mbox/commons-user/201205.mbox/browser).
I think it would be more straightforward assigning attributes to all nodes of a list. Otherwise the list feature seems incomlete to me.
Especially if your lists are a bit longish it would be very nice to avoid repeating tags in your config.xml.
