The value element
Release 2.0 - ...
When the value element appears as a child of element header, it is used to specify the value component of a header entry to be supplied to the submission protocol to be added to the preamble of a submission.
The value element may be used more than once in a given element header, in which case each value produces a new header entry.
The header entry value may be given by the string content of the value element, or by the result of the value attribute. If both are given, the result from the value attribute takes precedence.
