Vertica 7 - what level of SQL compliant it is - SQL92 / SQL99 / SQL2003 ?

The question is how far Vertica 7 supports the following. I am more interested about data types supprted than anything else.

From wikipedia,

SQL92 new features => data types date, timestamp, temporary tables
SQL99 => boolean data type, user defined types
SQL2003 =>  XML data type, merge statement

Thanks
