fi-0033: Conflicting modifiers {:#fi-0033}

Certain modifiers are mutually exclusive of one another and cannot both modify the same declaration:

{% include “docs/reference/fidl/language/error-catalog/label/_bad.md” %}

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0033.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}

Only one of the strict or flexible modifiers may be used on a single declaration at a time:

{% include “docs/reference/fidl/language/error-catalog/label/_good.md” %}

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0033.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}

At this time, only the strict and flexible modifiers are mutually exclusive in this manner. The resource modifier has no reciprocal modifier, and thus has no such restrictions applied to it.
