/**
* Wraps a {@link SchemaBuilder} and does all the semantic checks
* required by the RELAX NG spec.
*
* Usage
*
* Whereas you normally write it as follows:
*
* YourParsedPattern r = (YourParsedPattern)parseable.parse(sb);
*
* write this as follows:
*
* YourParsedPattern r = (YourParsedPattern)parseable.parse(new CheckingSchemaBuilder(sb,eh));
*
*
*
* The checking is done by using the rngom.binary package, so if you are using
* that package for parsing schemas, then there's no need to use this.
