Policy modules (other than the base) only support a subset of the
language, and fs_use_xattr is not supported in non-base module.
Thus, your options (as previously stated) are:
1) Grab the policy .src.rpm or upstream sources, modify them, and
rebuild, or
2) Use a context= mount to set a single fixed label on the entire mount.
