If a catalog exists and is allowed (not filtered out) for the given path, return
the catalog as an Catalog. Otherwise, return null.
<p>
The validity of the returned catalog is not guaranteed. Use Catalog.check() to
check that the catalog is valid.

@param path    the path for the requested catalog.
@param baseURI the base URI for the catalog, used to resolve relative URLs.
@return the requested Catalog, or null if catalog does not exist or is not allowed.
If a catalog exists and is allowed ( not filtered out ) for the given path return the catalog as an Catalog . Otherwise return null . <p > The validity of the returned catalog is not guaranteed . Use Catalog . check () to check that the catalog is valid .
