This specification does not define a set of legal meta data properties. The meaning of a property and the set of legal values for that property should be defined in a reference lexicon called a profile.
[å¼ç¨ï¼ HTML 4.01 Specification: Meta data ãã]
Authors may wish to define additional link types not described in this specification. If they do so, they should use a profile to cite the conventions used to define the link types.

Each
META element specifies a property/value pair. The name attribute identifies the property and the
content attribute specifies the property's value.
[å¼ç¨ï¼ HTML 4.01 Specification: The META element ãã]
The lang attribute can be used with META to specify the language for the value of the content attribute. This enables speech synthesizers to apply language dependent pronunciation rules.
