> Currently there is no way to convey through meta data that an attribute value 
> must conform to a particular pattern (for instance in the case of a hostname 
> or ip address).  
> Where a managed attribute is of type String, the regex can be used both 
> client and server side to validate the input.  Client side validation will 
> also always need to take into account that it is always legal to insert a 
> context variable reference into the value... and where such a context 
> injection is present is is effectively impossible to correctly validate on 
> the client side.
> For attributes which are of type Collection<String>, List<String> or 
> Set<String> the validValuePattern can be taken to be referring to the 
> validation applied to each element of the collection.
> The annotation information should also be conveyed through the metadataservlet
