The ISortClause type exposes the following members.

Serializes the object as xml to the writer specified.
Sets the CaseSensitiveCollation flag on the sort clause specified. This will apply the UPPER() function (or db specific equivalent) to the field in the ORDER BY clause.(Defined by SortClauseProducers.)
Sets the EmitAliasForExpressionAggregateField flag on the sort clause specified to false. The value of the flag indicates whether the alias of the field should be emitted if it has an expression/aggregate or the full field / expression. Using this method sets this flag to false indicating that the field in this sortclause isn't used in the projection and it has an expression/aggregate assigned to it.(Defined by SortClauseProducers.)
