XML schema [RC1] lacks stable keys for some elements

[donmendelson]

Most elements have an "id" or "name" attribute or both. However, certain XML elements lack a unique key that remains stable between version updates. Therefore, comparison of two files is not possible.

• Current practice is to identify the <protocol> element (formerly <fix>) by concatenation of FIX version and extension pack number. Therefore, the value changes after every modification, making it impossible to correlate in two files. Suggest adding "name" attribute that does not change with extension pack.

• Abbreviation element lacks an identifier. Suggest renaming "abbrTerm" to "name".

• Code element (formerly enum) lacks id or name. Suggest renaming "symbolicName" to "name".
