"include" ability in schema file?

[Yang]

I have a protocol schema  hello.avpr

{ ....
types: {
   { name : input_msg ,  type: record : fields [
        { name: date , type int },
       { name :msg, type: string}
    ]
  }

}

}


now if I need to serialize the record "input_msg", I'm going to need its
schema,
so I'd need to pass a schema obj to DataFileWriter. but how can I parse the
schema out from schema file?
the schema for "input_msg" is not a standalone file.

I would like a way to write the type of "input_msg" in a standalone file,
and then reference/include that from my hello.avpr.
is this possible?


also btw, for an avro-generate object class, would it be better to make the
getSchema() method static?
that way I can get its schema without creating an actual obj


thanks
