How Do I Get or Set Attributes with XFile?

XFile supports access to the file attributes supported by java.io.File, for instance: canRead, canWrite, isFile, isDirectory, lastModified, and length; however, as yet there is no mechanism for obtaining filesystem-specific attributes, for instance, the UID of an NFS file. Access to these attributes will be provided in future releases within the XFile ExtensionAccessor classes.
