tag-scheme
Contains the scheme (that is URI) of a tag
structure that may be used to tag content items of the type
represented by this element's parent
content-type
element. Client applications
such as CUE can use the presence of
tag-scheme
elements to determine which tags
they make available to users editing content items. CUE does not
display a Tags tab for content types that
have no tag-scheme
elements.
