ORA-DM-OTHERWISE 4.4.3 PSVI to Data Model mapping

*Data Model, Section 4.4.3 PSVI to Data Model mapping*

Under 'string-value' it says "The [schema normalized value] PSVI 
property if that exists, or the [normalized value] property." 
"Otherwise" would be better to use instead of "or", which implies that 
either one is acceptable.
