The allowed client or server location for a discoverable protocol must be a (possibly empty) comma separated list of platform and external. In other words one of:
"""platform""external""platform,external""external,platform"{% include “docs/reference/fidl/language/error-catalog/label/_bad.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0210.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
Make sure these arguments are correct:
{% include “docs/reference/fidl/language/error-catalog/label/_good.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0210.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
