User commentary
Please sign all comments.

I have found this program to be affordable, easy to use, and pre-loaded with TEI capabilities. Also, the platform gets upgraded on a regular basis. -- Greg Moses (Austin, TeiXas!)

System requirements
Runs under Windows, Linux, and Mac operating systems. Requires a Java VM (virtual machine).

(One of the download options for Windows users is an installer that includes the Java VM, eliminating the need to download and install Java separately.)

For detailed requirements, see http://www.oxygenxml.com/download.html.

Additional notes
David Sewell wrote ( http://listserv.brown.edu/archives/cgi-bin/wa?A2=ind0804&L=TEI-L&T=0&O=D&P=4227 ):

Because the schema files distributed with oXygen sometimes lag behind the latest TEI releases, kind souls like Syd Bauman have from time to time packaged new schema files so that they can be unpacked to replace part of the oXygen frameworks hierarchy. You could also go to

http://www.tei-c.org/release/xml/tei/custom/schema/relaxng/

and grab the files there to replace the ones in a local oXygen directory.

Sebastian Rahtz added that if you use Debian or Ubuntu, you should instead install the  package. He explained that "this replaces the oXygen TEI package with a link to one installed by the tei-p5-schema package, which is kept up to date. This means you have only one set of TEI files on your machine." It's available at tei.oucs.ox.ac.uk/teideb/.
