<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 serves both to suppress typical errors of the <block> element and to define typical error recovery actions. This element can be empty, in which case <catch> only suppresses typical errors.
