Definition: <META> is used in situations when the DTD is not extensible and strict SGML parsing is necessary. It embeds document meta-information that is not defined by other HTML elements, information that can be extracted by servers/clients for indexing, identifying, and cataloging.
NAME can be used to name a property such as date of publication or authorship. When it is not present, it is assumed to be the same as HTTP-EQUIV's value.
CONTENT supplies a value for a named property.
HTTP-EQUIV binds the element to an HTTP response header. When the semantics of the named HTTP response header are known, the contents can then be processed based on a well defined syntactic mapping, even if the DTD doesn't contain anything about it. If they are absent, the NAME attribute can be used to identify this meta-information, which should not be used within an HTTP response header. HTTP header names case insensitive.
Context: <META> is legal within
The following markup can be used within <META>: None
