| | RELAX NG - Wikipedia, the free encyclopedia |
 | | In computing, RELAX NG (REgular LAnguage for XML Next Generation) is a schema language for XML, based on Murata Makoto's RELAX and James Clark's TREX. | | | RELAX NG compact syntax is a non-XML format designed so that it can be unambiguously translated to its XML counterpart, and back again, with one-to-one correspondence in structure and meaning, in much the same way that Simple Outline XML (SOX) relates to XML. | | | RELAX NG shares with W3C XML Schema many features that set both apart from traditional DTDs: data typing, regular expression support, namespace support, ability to reference complex definitions. |

| | The Design of RELAX NG |
| | RELAX NG is a new schema language for XML. | | | RELAX NG is based on finite tree automata; this is an area of computer science that has been studied for many years and is accordingly mature and well understood. | | | Overall, RELAX NG is much more mature and it is possible to have a higher degree of confidence in its design than it would be if it were based on a completely different paradigm. |

| | RELAX NG (or RNG) is a schema language for XML. | | | The algorithm for RELAX NG is remarkably elegant, and is based on computing the derivative of a pattern. | | | A pattern P is nullable if the empty string (or empty tree) matches it. |

| | Relax NG schema for XSL FO |
| | Relax NG schema for XSL-FO has been created with two goals in mind: it should ensure fast and reliable validation; it should be convenient to use in visual XSL FO editors or document builders. | | | Fortunately, Relax NG allows ambiguity for attribute values (in a choice of two datatypes both can match) so no matter whether expression datatype is restrictive or not, the schema will remain valid. | | | The only serious disadvantage of Relax NG validation compared to its XSLT counterpart is inability to classify validity violations by severity and lack of context-sensitive error messages. |

| | RELAX NG Specification |
| | Although we use a notation based on the XML representation of an RELAX NG schema as a sequence of characters, the grammar must be understood as operating at the data model level. | | | A correct RELAX NG schema must be such that, after transformation to the simple form, it does not contain any element that matches a prohibited path. | | | Section 5 describes the syntax that results from applying the transformations; this simple syntax is a subset of the full syntax. |
