The xsdvalid distribution contains the XML Schema
( https://www.w3.org/TR/2001/REC-xmlschema-1-20010502/ )
validation engine that will be integrated into the 
future XMLmind XML Editor product
( https://www.xmlmind.com/xmleditor ).
This engine has been made available to schema and DTD
authors in the form of 3 command-line tools:
* xsdvalid: Checks an XML schema for validity. Checks an XML
  document for validity against an XML schema.
* dtdvalid: Checks a DTD for validity. Checks an XML document
  for validity against a DTD.
* dtdtoxsd: Converts a DTD to an XML schema.
The xsdvalid distribution can be downloaded from
https://www.xmlmind.com/xsdvalid.html .
Features:
* Fully implements XML Schema "Validation Rules".
* Fully implements XML Schema "Schema Component Constraint"
  and "Schema Representation Constraint" (except for a few --
  in our opinion, minor -- constraints).
* DTD and XML Schema support is provided by the same
  engine. In fact, the grammar part of a DTD (element,
  attribute and notation declarations) is loaded into the
  engine as if it was a schema.
* Once validated, a schema or a DTD can be serialized as a
  binary file for much faster reloading by XML document
  (instance) validation sessions.
Non features:
* Does not support anything related to XML Schema "Schema
  Information Set Contribution".
* This engine is designed to be an interactive, incremental
  validator and not a streaming one. Therefore, it needs to
  load the entire XML document into memory before attempting
  to perform validation.
