We know and like NVDL but we find it overkill for the most common needs.

See http://www.xmlmind.com/xmleditor/_distrib/doc/configure/validate.html We currently use this feature: * to ``inject'' the MathML schema into the DITA DTD and the DocBook 5 RELAX NG schema. * to ``inject'' the XHTML DTD into various schemas such as the Schema for W3C XML Schemas (this allows us to document a W3C XML schema using XHTML). DITA example. Excerpts from mathml_config/ditamml/ditamml.xxe: --- <configuration name="DITA" ...> ... <include location="xxe-config:dita/topic.xxe" /> <validate namespace="http://www.w3.org/1998/Math/MathML";> <relaxng location="../common_rng/mathml2.rng" /> </validate> --- WXS example. Excerpts from wxs_config/wxs.xxe: --- <configuration name="W3C XML Schema" ...> ... <schema> <location>http://www.w3.org/2001/XMLSchema xsd/XMLSchema.xsd</location> </schema> <validate namespace="http://www.w3.org/1999/xhtml";> <dtd publicId="-//W3C//DTD XHTML 1.0 Strict//EN" systemId="xxe-config:xhtml/dtd/1.0/xhtml1-strict.dtd" /> </validate> --- However, you cannot use this feature unless: [1] Your DTD has an ANY element which can be used to host x elements. More generally the main schema must have elements which can be used to host elements coming from the secondary schemas. [2] The XML Schema for "x" has a target namespace. Notice that the <validate> configuration element requires one --and only one-- namespace. However XXE supports several different <validate> configuration elements in the same configuration file. -- XMLmind XML Editor Support List [email protected] http://www.xmlmind.com/mailman/listinfo/xmleditor-support
