validate(ValidationInformation info)
This method is called whenever it has been determined that a validating
class is to be injected into an injection point, or when a descriptor
is being looked up explicitly with the API, or a descriptor is being
bound or unbound into the registry.

boolean validate(ValidationInformation info)
The candidate descriptor being passed in may not have yet been reified. If possible, this method should do its work without reifying the descriptor. However, if it is necessary to reify the descriptor, it should be done with the ServiceLocator.reifyDescriptor method.
The operation will determine what operation is being performed. In the
BIND or UNBIND cases the Injectee will be null. In the LOOKUP case
the Injectee will be non-null if this is being done as part of an
injection point. In the LOOKUP case the Injectee will be null if this
is being looked up directly from the ServiceLocator
API, in which
case the caller of the lookup method will be on the call frame.
