#268 Provide better MBean descriptions

[Heiko W.Rupp]

Allow to have MBean Descriptions stored in
server/.../conf/xmdesc/ as XMBeans.
This serves to give better descriptions of MBean
operations and attributes to the end user calling the
MBean Views in JMX console.
Jboss_xmbean_1_1.dtd is a clone of the 1.0 version with
two entities 'defops' and 'defattrs' for the default
Mbean operations and attributes.
JNDIView-xmbean.xml is the first MBean-'Description'
file which is meant as example and also uses the new
DTD and its two entites.

Please keep with standardized XML naming rather than mixing
more naming styles into same schema.

defaultOperations and defaultAttributes

What are these defaults for?

Ok wrt. naming.
The defaults are for providing an easier way to developers in
writing XMBeans, as the lifecycle methods and state attribute
(s) can be written as an XML entity rather than writing them
completely out each time.

Yes saw that, it is a good idea.

Thanks.
