REgular LAnguage description for XML (RELAX) is a specification for describing XML-based languages. A description written in RELAX is called a RELAX grammar.
RELAX Core has been approved as an ISO/IEC Technical Report 22250-1 in 2002 (ISO/IEC TR 22250-1:2002). It was developed by ISO/IEC JTC1/SC34 (ISO/IEC Joint Technical Committee 1, Subcommittee 34 - Document description and processing languages).
RELAX was designed by Murata Makoto.
In 2001, an XML schema language RELAX NG was created by unifying of RELAX Core and James Clark's TREX. It was published as ISO/IEC 19757-2 in 2003.
Famous quotes containing the words regular, language and/or description:
“He hung out of the window a long while looking up and down the street. The world’s second metropolis. In the brick houses and the dingy lamplight and the voices of a group of boys kidding and quarreling on the steps of a house opposite, in the regular firm tread of a policeman, he felt a marching like soldiers, like a sidewheeler going up the Hudson under the Palisades, like an election parade, through long streets towards something tall white full of colonnades and stately. Metropolis.”
—John Dos Passos (1896–1970)
“He never doubts his genius; it is only he and his God in all the world. He uses language sometimes as greatly as Shakespeare; and though there is not much straight grain in him, there is plenty of tough, crooked timber.”
—Henry David Thoreau (1817–1862)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
