A resource_definition declaration's properties must not repeat canonical names:
{% include “docs/reference/fidl/language/error-catalog/label/_bad.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0109.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
The correct rendering of this declaration has exactly one subtype property and zero or one rights properties:
{% include “docs/reference/fidl/language/error-catalog/label/_good.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0109.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
See fi-0035 for more details on why FIDL requires declarations to have unique canonical names.
This is an error related to FIDL‘s internal implementation, and thus should only ever be surfaced to developers working on FIDL’s core libraries. End users should never see this error.
The resource_definition declaration it refers to is FIDL's internal means of defining resources like handles, and is likely to change in the future as part of the handle generalization effort.
