Draft for accompanying document
We want to create an accompanying document for LIDO v1.1 covering additional information which shouldn't be listed in the schema docs.
At this moment, this includes:
- introductory texts
- listing the following information per element (where applicable):
- further information
- data values
- equivalent elements in other schemas
