OFDAxml does:

• Use identifiers that provide clues to the meaning of the content.  Readibility is more
  than tag length.
  
  
• Use the Upper Camel Case capitalization style for all XML constructs other than attributes
  in which the first letter in the identifier and the first letter of each subsequent concatenated
  word are capitalized.  Used for names of three or more characters.  For example: DateRequired.
  
  
• Use the Lower Camel Case capitalization style for attribute names in which the first letter in the identifier is in lower case and the first letter of each subsequent concatenated word are
  capitalized.  Used for attribute names of three or more characters.
  
  
• Append the word "Type" to all names of simple types.
  
  
• Use well-known acronyms to replace lengthy phrase names where appropriate.  For
  example, ItemSKU instead of ItemStockKeepingUnit.
  
  
• Use Upper Camel Case for acronyms of three or more characters.  However, acronyms that
  consist of only two characters should be capitalized.  For example: ContractID
  
  
• Use names, not numbers, for enumeration values.  The names used for enumeration values
  must conform to the guidelines for element or attribute names.
  
  
• Prefer ISO standards to national or consortium specifications.

OFDAxml does not:

• Use names that require case sensitivity.
  
  
• Create identifiers with names that differ only by case.
  
  
• Use abbreviations or contractions as parts of identifier names.  For example, use 
  TaxNumber instead of TaxNum.
  
  
• Use acronyms that are not generally accepted outside of the office furniture industry. For example, SIF.
  
  
• Include a repetition of the name of a containing structure in the name of an element. For example, a <Customer> element could contain a <Name> element but should not contain a <CustomerName>element.
