0029846: Data Exchange - STEP validation properties support is obsolete

Browse Source 
Name of the PROPERTY_DEFINITION entity for validation properties is changed to "geometric validation property" according to the current version of the recommended practices.
For compatibility with older definitions (with underscores) the check is made using string with underscores replaced by spaces.
