Header   - The top level tag that marks the beginning of the header information.
copyright    - This head attribute contains the copyright information for this model.
description - This head attribute contains a non-specific description the for the model. It should contain information necessary to use this model in further applications, but not information that could be better defined in the application element, annotation, and the data dictionary section.  This attribute should only contain human readable information, and models included with this dtd should not be expected to utilize the information contained in this attribute.

Application - This head element describes the software application that generated the PMML.  Though these models are created to be portable, different mechanisms may create different models from the same data set.  It is of interest to the user from which application these models were generated.
    name     - The name of the application that generated the model
    version   - The version of the application that generated this model

Annotation - Document modification history is embedded here. Each annotation is free text and, like the description attribute in the head element, makes sense to the human eye only.

Timestamp - This element allows a model creation timestamp in the format YYYY-MM-DD hh:mm:ss GMT +/- xx:xx.
