xz isn't an archiver, that is, it cannot pack multiple files into a
single file. tar is an archiver but it isn't a compressor. To archive
and compress, you can use tar and xz together:
tar cf - /etc | xz > etc.tar.xz
GNU tar and BSD tar can call xz themselves:
tar caf etc.tar.xz /etc
Maybe you have used .zip or .7z files. With such file formats the
archiving, compression, and possibly also encryption are done by a
single file format and tool. When using tar with gzip/bzip2/xz/whatever
the tasks are done by separate file formats and tools.
