Subject: [PATCH] Allow cancel of alert via API with no description

The XML for an alerts requires a `<description>` field. The XML for
a `<cancel>` may have a `<description>` field populated (although we
ignore the contents) but it may also be empty.

This commit updates the schema to leave the all the validation to the
view layer, which can decide when or when not to validate the content of
the `<description>` field.
