'''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 was designed by [[Murata Makoto]].

In 2001, an XML schema language [[RELAX NG]] was created by unifying of RELAX Core and [[James Clark (programmer)|James Clark]]'s TREX.<ref>{{cite web |url=http://www.thaiopensource.com/trex/ |title=TREX - Tree Regular Expressions for XML - "TREX has been merged with RELAX to create RELAX NG." |author=James Clark |accessdate=2009-12-28}}</ref><ref>{{cite web |url=http://www.xml.gr.jp/relax/ |title=RELAX (Regular Language description for XML) -- "RELAX NG of OASIS.
