SQL-92 Compliant

Being new to Oracle, I need to know something:

How compliant is Oracle7 with the SQL-92 standards? Can I get a white paper on this from Oracle or somewhere? I don't think 7.1 supports the "join" and "left/right outer join" keywords (I have a lot of code that using this in a MS SQL Server environment). Does 7.3 support this syntax? What other syntax is (is not) supported?

Thanks in advance!
