Please add the Schema Object Model (SOM) interface into the
1)The jaxp lack the access to the schema grammar.
2)There is a problems to extend the validator's capabilities using
xs:annotation/xs:appInfo xsd enhancement mechanism.
.Net has such capability. Java world has at least 2 implementation of the SOM.
com.sun.xsom (xsom.dev.java.net) and org.apache.ws.commons.schema.XmlSchema
But neither xsom nor XmlSchema can't be used for validation. So it will be nice
to incorporate such capability directly into the javax.xml.validation.Schema.
