## Developer's Guide

> The Sun Multi-Schema Validator(MSV) is a JavaTM technology tool to validate XML documents against a variety of XML schemata. It supports RELAX Namespace, RELAX Core, RELAX NG, TREX, XML DTDs, and a subset of W3C XML Schema Part 1.

## Simple API for MSV

> Most of the time, you just need plain simple validation and nothing else. If so, you can use JARV, an implementation-independent, simple and easy interface set.

> More information about JARV is available here.

## JAXP masquerading

> If you have existing code that works with JAXP and you don't want to change it, then you should have a look at the JAXP-masquerading feature of MSV.

## Native API

> If you need even more control over the validation process (for example, you are developing a schema-related tool), then you may want to understand the native API of MSV. For more information, read this document.
