Pre-initialize property Names. | |
These properties are pre-initialized once to reduce property validation overhead. Note that the InitialNumberReplicas and MinimumNumberReplicas properties are not validated since there are no restrictions imposed by TAO's PortableGroup implementation regarding the number of such members. | |

Default property validator implementation.
This Property_Validator verifies that all properties defined in the PortableGroup IDL module are valid. This property validator can be subclassed to validate a different property set.
