Implements attributed features, that is in the simplest case a number of (attribute, value) pairs.
For example
x[0...].attr1 = <value(s)> x[0...].attr2 = <value(s)>.
A more complex example would be nested structures x[0...].attr1[0...].subattr1 = ..
This might be used to represent (attr, value) pairs, simple structures, trees ...
