// Schema for DECL_ATTR:
//
// - Attribute name.
// - Class name without the 'Attr' suffix (ignored for
// - Options for the attribute, including:
// * the declarations the attribute can appear on
// * whether duplicates are allowed
// * whether the attribute is considered a decl modifier or not (no '@')
// - Unique attribute identifier used for serialization. This
// can never be changed.
//
// SIMPLE_DECL_ATTR is the same, but the class becomes
// SimpleDeclAttr<DAK_##NAME>.
//
// Please help ease code review/audits:
// - Please indent once, not to the opening '('.
// - Please place the "OnXYZ" flags together on the next line.
// - Please place the non-OnXYZ flags together on the next to last line.
// - Please place the unique number on the last line. If the attribute is NOT
// serialized, then please place that flag on the last line too. For example:
// 123)
// NotSerialized, 321)
// - Please sort attributes by serialization number.
// - Please create a "NOTE" comment if a unique number is skipped.
