XTCE12 — Possible unused attribute in RepeatEntry

The RepeatEntry has a count element (required) and an offset element (optional). The offset element has four choices: offsetSizeInBits (attribute), FixedValue, DynamicValue, DiscreteLookupList (elements).

The first item there seems a sore thumb... further you can easily say two conflicting things with it.

The offsetSizeInBits is probably an vestige from an earlier version of the schema and can be removed.

Propose to remove the redundant attribute

OffsetType is only used in RepeatType. Eliminate OffsetType from the schema and define the Offset element in
RepeatType as an IntegerValueType.

Delete complexType OffsetType:

Replace element Offset in complexType RepeatType:
<complexType name="RepeatType">
...
<sequence>
...
<element name="Offset" type="xtce:OffsetType" minOccurs="0"/>
</sequence>
</complexType>

with the element:
<element name="Offset" type="xtce:IntegerValueType" minOccurs="0"/>
