Re: Schema target name space (& Sun's IP)

[Aaron Mulder <am...@alumni.princeton.edu>]

	Another issue that I just noticed is that we have copied Sun's web
Schema into the Geronimo Web schema (see geronimo-web-app.xsd) including
the Sun copyright and the part saying you can't reproduce it without prior
written consent from Sun.  I suspect we ought to remove this and replace
it with something more like the geronimo-ejb-jar.xsd
