Note: The different TagsSupportedBy-categories are not complete and the level of support for the tags may vary. These categories are ment as a hint about how well supported a given tag is by applications (as opposed to how often it is mapped) and what applications may be involved if the semantics are to be extended or changed.
The categories below document how well a given tag is supported by applications (renderers, navigation-apps, editors, ...)
