Replace the buggy schema parser by one based in GTXML and EMF-XSD
-----------------------------------------------------------------
Key: GEOT-1324
URL: http://jira.codehaus.org/browse/GEOT-1324
Project: GeoTools
Issue Type: Task
Components: new modules
Affects Versions: 2.4.0
Reporter: Gabriel Roldán
Assignee: Gabriel Roldán
Fix For: 2.4.0
At the time the complex-features branch was created, the were no an existing
parser to get {{FeatureType}}s out of a community schema in XML Schema files,
so we used a quick, dirty and ugly one with lots of limitations.
Now the scenario is completely different, GTXML can be used together with EMF,
as it fits perfectly as FeatureType metadata so we don't lose a single bit of
the actual community schema we're working with, since the emf type definition
object in the schema can be stored as a "userData" property for each
FeatureType, as well as the emf element declaration for each
AttributeDescriptor.
This information could well serve at a later step to actually be able to
creating valid GML documents for the community schema by the use of a schema
assisted encoder.
So we just have thrown away the old and ugly schema parser, which won't work
anyway due to the FM API shift, in favor of a new, emf based one, that reuses
the GML to FeatureType bindings in GeoTools.
Note that since these bindings exists for the current GeoTools Feature Model,
we're again using adapters to go from geotools FeatureTypes to ISO
FeatureTypes. This situation is temporary though, and should last only until
the ISO Feature model is adopted, in which case the GML bindings are going to
be ISO FeatureTypes by them selves.
