HyperText Mark-up Language

HTML

The WWW system uses marked-up text to represent a hypertext document for transmision over the network. The hypertext mark-up language is an SGML format. WWW parsers should ignore tags which they do not understand, and ignore attributes which they do not understand of tags which they do understand.
