This pages describes features, codes or syntax whose use is now DEPRECATED, i.e. not advised either for new or continued pre-existing use.
Deprecated aspects of Tinderbox may be supported on a legacy basis but the latter support can't be presumed to be indefinite. Therefore you should update your active TBX documents to latest practice as soon as practical.
The designator sibling describes all notes at the same outline level as the current note that share a common parent. From v5.8.0, deprecated in favour of siblings.
Designators don't allow offset references as with attributes. Thus $Name("Some note") works but children("Some note") doesn't. If an offset designator is needed use find() instead.
