Basically when we talk about validators we are probably talking about some 
component that validates configuration. So we may have DTD validator that 
makes sure a component conforms to a DTD or XSchemaValidator that makes sure 
it conforms to an XML Schema.

However we may also mean it as a general purpose component that makes sure 
data conforms to specific rules. ie a Form validator would make sure that the 
input parameters to GUI/servlet/other conform to a set of rules (ie all 
fields supplied and validly formatted).

It is a different Context.  Cocoon caching is looking
at using Excalibur's Monitor so that it can be notified
of changes to the source files on disk so the Cache can
remove the entry automatically.

In the Cocoon MRUStore (cache) parlance, a validator is
the object that identifies a cache entry as up to date.

See the thread
	RE: excalibur scratchpad: cache support
in this thread word validator was used in the
relation to the excalibur.Monitor

but maybe it's a different context. I didn't found
this word in the whole avalon documentation. So
I get a little curiously.
