             Summary: add pipes as binding provider for a given pipe
                 Key: SLING-8126
                 URL: https://issues.apache.org/jira/browse/SLING-8126
             Project: Sling
          Issue Type: Improvement
          Components: pipes
    Affects Versions: pipes 3.0.2
            Reporter: Nicolas Peltier


additional bindings are for now too rigid: 
- you can only add them at the root pipe level
- their value is an expression, which is cool but often not practical: you might need a specific resource in the current execution context. ideal would be to add a pipe as a provider to fetch it.

Proposal is:
# allow additionalBindings & additionalScripts nodes in all pipes & subpipes of a pipe declaration, like global & local scope variables,
# allow additionalBindings/providers subnode, that will be a set of pipe to execute in parallel in the current context (sharing pipe's binding), taking the first resource returned as binding value, the pipe name as binding name
