                DERBY2722_set_collation_for_xmlserialize_char_varchar_functions_v1_diff.txt

Committed attached patch DERBY2722_set_collation_for_xmlserialize_char_varchar_functions_v1_diff.txt with revision 543183. The commit comments are as follows

DERBY-2722
Committing changes which will make sure that we set the collation to current schema's collation for the return character string from XMLSERIALIZE. Don't have to make any changes for CHAR and VARCHAR functions because these functions gets translated into CAST by the parser and I have already checked in changes for the result of CAST to have the collation of current schema.

> As per the wiki page http://wiki.apache.org/db-derby/BuiltInLanguageBasedOrderingDERBY-1478, assign correct collation type for results of CHAR, VARCHAR and XMLSERIALIZE functions. The rule as copied from the wiki page is as follows
> 6)CHAR, VARCHAR and XMLSERIALIZE functions do not look like they are defined in the SQL spec. Their behavior can be defined as similar to CAST ie, the result character string of CHAR/VARCHAR/XMLSERIALIZE will have the same collation as current schema's character set. The collation derivation will be implicit.
