> I've been working with the initial MR for Logical Types and notice that as
> written the code doesn't support the following form of fixed decimal
>
> {code:java}
> {
> "name": "decimal_9",
> "type": "fixed",
> "size": 4,
> "logicalType": "decimal",
> "precision": 9,
> "scale": 2"
> }
> {code}

> The exception is currently:
> Avro.Test.LogicalTypeTests.TestFixedDecimal("-000000000000000001.01")
> Avro.SchemaParseException : Undefined name: fixed at 'type'

> The usage of the above scenario is very powerfull if implementations, where
> you have hundreds of uses of decimal values where you want them to all,
> support the same specification. I'm still looking at the code to understand
> what the best answer would be but it would need to be some form of named
> logical scheme.
