<catch> Element

The <catch> element is a child element of the <try> step. This element specifies the steps to execute if a typical error occurs while executing the steps of the <block> element. The <catch> element can contain any number of steps that are permitted within the scope of the block that contains the <try> step.

The <catch> element suppresses typical errors of the <block> element and defines typical error-recovery actions. When the <catch> element is empty, it only suppresses typical errors.
