Sure you can define types programmatically... it's just that for the
case of types, defining them through XML is actually more convenient.
Mind that the type-system is implementation independent! You can think
of it as of an DTD or XSD.
If you want to programmatically create a type, you can do this:
TypeSystemDescription tsd = new TypeSystemDescription_impl();
TypeDescription tokenTypeDesc = tsd.addType("Token", "",
CAS.TYPE_NAME_ANNOTATION);
tokenTypeDesc.addFeature("length", "", CAS.TYPE_NAME_INTEGER);
CAS cas = CasCreationUtils.createCas(tsd, null, null);
cas.setDocumentText("This is a test.");
