Syntax

Argument	Rules	Description
type	Mandatory	cast
operand	Mandatory	the resource to be serialized to the log
operator	Mandatory	the cast specification
target	Mandatory	the target resource

The cast accessor is used to specify the Mimetype of the operand resource. This can be useful when a representation of a resource can have more than one equally valid form. For example an XML resource could be equally valid as text/xml, text/html, text/xhtml or text/plain depending upon the context of the response.

Cast does not change the resource it simply changes the meta data associated with a resource.

Operator Syntax

The cast accessor takes an operator which specifies the cast.

mimetype is any valid mimetype.
