  3)BasicDatabase needs to set the Locale value in the DVF after DVF has booted. DERBY-2535
Make Locale available in DataValueFactory(DVF). This Locale object will be used to construct
Collator object if the user has requested territory based collation. Changes went in as part
of revision 527034
  
+ 4)The check to see if two types are comparable or not has been moved out from TypeCompiler
into DTD. The new interface in DTD is aptly called "comparable". The reason for this move
is while comparing 2 types, now we should check that collations match too when dealing with
string types. TypeCompiler does not have collation information and hence the comparable method
in it couldn't use collation in determining the result of the comparable method. That is why
the comparable method got removed from TypeCompiler. DTD has the collation information and
hence it is the right candidate for the comparable method. DERBY-2569 revision 530910
+ 
  '''[[GetText(Data Dictionary)]]'''
  
  1)Set the correct collation type in SchemaDescriptor. On this page, Section Collation Determination,
item 2) says that column definitions pick up their collation from the schema that they are
defined in. In order for that to happen, schema should have the right collaiton type associated
with it. This work of attaching right collation type to a schema went in as part of DERBY-2528
with revision 526237, 526243 and 526313.
