fi-0015: Attribute args must all be named {:#fi-0015}

For clarity, when an attribute has more than one argument, all of the attribute's arguments must be explicitly named.

This error occurs when an attribute has more than one argument but does not explicitly provide names for the arguments.

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

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0015.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}

To fix it, provides names for all of the arguments using name=value syntax.

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

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0015.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}

Note: This does not apply if an attribute has just a single argument.
