Authors may use the following recognized link types, listed here with their conventional interpretations. A LinkTypes value refers to a space-separated list of link types. White space characters are not permitted within link types. These link types are case-insensitive, i.e., "Alternate" has the same meaning as "alternate".
User agents, search engines, etc. may interpret these link types in a variety of ways. For example, user agents may provide access to linked documents through a navigation bar.

Script data can be the content of the "script" element and the value of intrinsic event attributes. User agents must not evaluate script data as HTML markup but instead must pass it on as data to a script engine.
The case-sensitivity of script data depends on the scripting language.
Please note that script data that is element content may not contain character references, but script data that is the value of an attribute may contain them.

Arbitrary textual data, likely meant to be human-readable.
Transparent elements. Such elements have a part of they children in their data and behaves like them. We could do something like a: 'a elt list -> 'a elt but the information about the node name would be forgotten and would allow things like that : p [a [a []]]. This system allow to build non-conforming terms such as a [a []] but when passed to a standard element (such as p), it will yield an error. Exception to that : if you embdedd the element in another transparent (of an another kind) : p [noscript (a [a []])] will be correctly typed.
