What you want is a "complex feature", represented by the Feature class.
There is no good support in terms of creating one of these, something is
moving on trunk right now
but I'm not sure if 9.0 will have support on part with simple features or
not.
In the meantime, still on trunk, I needed to build complex features to
support the CSW work
in GeoServer so I've picked and adapted a few classes here:
https://github.com/geoserver/geoserver/tree/master/src/community/csw/csw-api/src/main/java/org/geotools/feature
Even with those building a particular type of feature is still a lot of
work, so I also created specialized
builders helping with the job. Here is some code the CSW dublin core
feature type, and
a builder to simplify the construction of one of its features:
https://github.com/geoserver/geoserver/blob/master/src/community/csw/csw-api/src/main/java/org/geoserver/csw/records/CSWRecordDescriptor.java
https://github.com/geoserver/geoserver/blob/master/src/community/csw/csw-api/src/main/java/org/geoserver/csw/records/CSWRecordBuilder.java
Hope this helps
Cheers
Andrea
