Eliminating redundant data in Orchestra files

[Olivercomputing]

The ancestor of Orchestra files, the Fix Repository, contains redundant information. For example, a field reference:

<fixr:fieldRef id="5" name="AdvTransType" presence="required" added="FIX.2.7"> [...]

And then a related field definition entry:

<fixr:field id="5" name="AdvTransType" type="AdvTransTypeCodeSet" added="FIX.2.7" abbrName="AdvTransTyp"> [...]

The name attribute in the fieldRef element is redundant. It should always match the name in the field definition. This denormalization is unnecessary and wasteful. The id attribute is sufficient to specify the field reference.

The same also applies to components and groups, and there may be other similar examples.

In GroupType, keep attribute numInGroupId but remove numInGroupName since it is redundant.
