> Currently, in Derby 10.2, we generate SQLChar/SQLVarchar/SQLLongvarchar/SQLClob for various
SQL character types. All these DVDs have the default collation of UCS_BASIC. 
> Starting 10.3, we should look at the collation type of the DTD before deciding what kind
of DVD gets generated for SQL character types.  If the collation type of the character type
is terriotry based collation, then we should generate CollatorSQLChar/CollatorSQLVarchar/CollatorSQLLongvarchar/CollatorSQLClob
rather than SQLChar/SQLVarchar/SQLLongvarchar/SQLClob. The CollatorSQLxxx DVDs will have the
territory based collator associated with them and hence the collation order of these DVDs
will be different than the DVDs with default collation of UCS_BASIC.
