You saved me a few more hours of tracking down the cause, thanks!

Is this same error message somehow related to https://github.com/danielgtaylor/aglio/issues/237 ?

drafter produce warning message by both This PR and #237.

$ drafter test.apib
element: "parseResult"
content:
  -
    element: "annotation"
    meta:
      classes:
        - "warning"
    attributes:
      code: 4
      sourceMap:
        -
          element: "sourceMap"
          content: []
    content: "ExtendElement must be composed from Elements of same type"

OK.
warning: (4)  ExtendElement must be composed from Elements of same type

So, it seems to me that aglio has no responsibility of this problem. I withdraw this PR. Thanks.
