<vDefault>

<vDefault> (value default) declares the default value to be supplied when a feature structure does not contain an instance of f for this name; if unconditional, it is specified as one (or, depending on the value of the org attribute of the enclosing fDecl) more fs elements or primitive values; if conditional, it is specified as one or more if elements; if no default is specified, or no condition matches, the value none is assumed.
