> Key: DAFFODIL-1927
> URL: https://issues.apache.org/jira/browse/DAFFODIL-1927
> Project: Daffodil
> Issue Type: New Feature
> Components: Back End
> Affects Versions: 2.2.0
> Reporter: Mike Beckerle
> Priority: Critical
> Fix For: 3.2.0
>
>
> Pluggable layering transforms, rather than registering them in a singleton object.
> We might want to use the java Services API for this kindof thing. Would prevent users from having to call the register function--just need to put a special file in the META-INF directory in the jar file.
> See the file LayerTransformer.scala.
