I can't currently see a way to extract the titles from the WFSCapabilities
document, you would need something like:
WFSClient client = wfsFeatureSource.getWFS();
WFSGetCapabilities cap = client.getCapabilities();
for(EObject obj:cap.getParsedCapabilities().eContents()) {
//examine object to find featuretype and extract title
}
