Attributes
This section contains definitions for commonly-used attributes. If an attribute is defined differently on a specific element, that information is covered in the topic for the specific element.
Note (non-normative):
In some cases, an attribute might mean different things on different
elements. If an attribute does not use the common definition for a given element, it will be
noted in the topic describing that element. For example,
@type is often used on linking elements to describe the target of the
link, but it is also used on <note> elements to describe the type
of note.
