- <!-- introduction -->
+ &clsql; provides and uses a condition system in which all errors
+ and warnings are of type <link
+ linkend="sql-condition"><errortype>sql-condition</errortype></link>. This
+ section describes the various subclasses of <link
+ linkend="sql-condition"><errortype>sql-condition</errortype></link>
+ defined by &clsql;. Details are also provided for how they are
+ used in &clsql; and intended to be signalled in user
+ code. Finally, slot accessors for some of the condition types
+ are described.
