# Schema Interfaces

## Overview

This package is intended to provide all the necessary interfaces to semantically represent an XML Schema. Some of the concious shortcomings of this interface set include the in-ability to reproduce exact xml schema documents from a schema represented in memory using just these interfaces (some non-essential constructs have been removed/ignored).

Implementors creating instances of this package should refer to the SchemaFactory (org.geotools.gml) to link your implmentation into the parser.

## How to make an extension

This is easy to describe, but hard to implement (or rather to test + debug). Essentially you should create a class that implements Schema, and register it with the SchemaFactory. When creating the appropriate Types as part of the Schema (I assume your Schema will have these) you can link extra parsing into the getValue method (see Type Interface).
