All Implemented Interfaces:
  `Cloneable`

public class SchemaValidate extends XMLValidateTask
Validate XML Schema documents. This task validates XML schema documents. It requires an XML parser that handles the relevant SAX, Xerces or JAXP options. To resolve remote references, Ant may need its proxy set up, using the setproxy task. Hands off most of the work to its parent, `XMLValidateTask`

Since:
  Ant1.7

- ## Method Details

  - ### init

    public void init() throws BuildException
    Called by the project to let the task initialize properly. The default implementation is a no-op.
    Overrides:
      `init` in class `XMLValidateTask`
    Throws:
      `BuildException` - if something goes wrong with the build

  - ### enableXercesSchemaValidation

    public boolean enableXercesSchemaValidation()
    Turn on XSD support in Xerces.
    Returns:
      true on success, false on failure

  - ### enableJAXP12SchemaValidation

    public boolean enableJAXP12SchemaValidation()
    Set schema attributes in a JAXP 1.2 engine.
    Returns:
      true on success, false on failure
    See Also:
      JAXP 1.2 Approved CHANGES

  - ### addConfiguredSchema

    public void addConfiguredSchema​(SchemaValidate.SchemaLocation location)
    add the schema
    Parameters:
      `location` - the schema location.
    Throws:
      `BuildException` - if there is no namespace, or if there already is a declaration of this schema with a different value

  - ### setFullChecking

    public void setFullChecking​(boolean fullChecking)
    enable full schema checking. Slower but better.
    Parameters:
      `fullChecking` - a `boolean` value.

  - ### createAnonymousSchema

    protected void createAnonymousSchema()
    create a schema location to hold the anonymous schema

  - ### setNoNamespaceURL

      `createDefaultReader` in class `XMLValidateTask`
    Returns:
      a default XML parser

  - ### addSchemaLocations

    protected void addSchemaLocations()
