Restructure Section 3, Guide to the Schema Structures

'Definition' column in this table of various schema types is actually a continuation of the descriptions in bulleted list above this table.
Suggest merging these sections of information and either :

• do not use table structure, use bulleted or subheadings instead and make each of those into separate paragraphs as already in the paragraphs above
  or
• use table structure, including all information in the table, and change the 'Definition' column heading to something else, such as 'Description', 'Components', or any other term so as not to confuse with the Element Definitions. The information in that column is not a definition, is more of a description.

Really best to do something that distinguishes as separate from the Element tables.
