little transformation or loss of information as possible while at the same time simplifying
station metadata representation when possible. Also, content and clarification has been added
where lacking in the SEED standard.

When definitions and usage are underdefined the SEED manual should be referred to for
clarification. SEED specifiation: http://www.fdsn.org/publications.htm

Another goal is to create a base schema that can be extended to represent similar data types.


Versioning for FDSN StationXML:

The 'version' attribute of the schema definition identifies the version of the schema. This
version is not enforced when validating documents.

The required 'schemaVersion' attribute of the root element identifies the version of the schema
that the document is compatible with. Validation only requires that a value is present but
not that it matches the schema used for validation.
