In the change to generalize the deployer suffix management, the acceptance of deployable content has relaxed a bit as the MainDeployer suffixes are not as precise as they should be. For example, any descriptor seen to end in ds.xml is seen as deployable based on the SubDeployerSupport.isDeployable method, even though the XSLSubDeployer only accepts -ds.xml suffixes. This results in spurious IncompleteDeploymentExceptions about no deployer for descriptors like fields.xml.

We should probably not have any default suffix list and simply let it be built by the registration of the sub deployers.
