  Parameters:
    `is` - The InputSource containing the content to be parsed.

### getSchema

    public javax.xml.validation.Schema getSchema()

  Description copied from class: `javax.xml.parsers.SAXParser`

  Get a reference to the the `Schema` being used by the XML processor.

  If no schema is being used, `null` is returned.

  Overrides:
    `getSchema` in class `javax.xml.parsers.SAXParser`
  Following copied from class: `javax.xml.parsers.SAXParser`
  Returns:
    `Schema` being used or `null` if none in use

    `UnsupportedOperationException` - For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown.

### reset

    public void reset()

  Description copied from class: `javax.xml.parsers.SAXParser`

  Reset this `SAXParser` to its original configuration.

  `SAXParser` is reset to the same state as when it was created with `SAXParserFactory.newSAXParser()`. `reset()` is designed to allow the reuse of existing `SAXParser`s thus saving resources associated with the creation of new `SAXParser`s.

  The reset `SAXParser` is not guaranteed to have the same `Schema` `Object`, e.g. `Object.equals(Object obj)`. It is guaranteed to have a functionally equal `Schema`.

  Overrides:
    `reset` in class `javax.xml.parsers.SAXParser`

### getElementPSVI

    public org.apache.xerces.xs.ElementPSVI getElementPSVI()

  Description copied from interface: `org.apache.xerces.xs.PSVIProvider`
  Provides the post schema validation item for the current element information item. The method must be called by an application while in the scope of the methods which report the start and end of an element. For example, for SAX the method must be called within the scope of the document handler's `startElement` or `endElement` call. If the method is called outside of the specified scope, the return value is undefined.
  Specified by:
    `getElementPSVI` in interface `org.apache.xerces.xs.PSVIProvider`
  Following copied from interface: `org.apache.xerces.xs.PSVIProvider`
  Returns:
    The post schema validation infoset for the current element. If an element information item is valid, then in the post-schema-validation infoset the following properties must be available for the element information item: The following properties are available in the scope of the method that reports the start of an element: {element declaration}, {validation context}, {notation}. The {schema information} property is available for the validation root. The {error codes} property is available if any errors occured during validation. The following properties are available in the scope of the method that reports the end of an element: {nil}, {schema specified}, {normalized value},{ member type definition}, {validity}, {validation attempted} . If the declaration has a value constraint, the property {schema default} is available. The {error codes} property is available if any errors occured during validation. Note: some processors may choose to provide all the PSVI properties in the scope of the method that reports the end of an element.

### getAttributePSVI

    public org.apache.xerces.xs.AttributePSVI getAttributePSVI(int index)

  Description copied from interface: `org.apache.xerces.xs.PSVIProvider`
  Provides `AttributePSVI` given the index of an attribute information item in the current element's attribute list. The method must be called by an application while in the scope of the methods which report the start and end of an element at a point where the attribute list is available. For example, for SAX the method must be called while in the scope of the document handler's `startElement` call. If the method is called outside of the specified scope, the return value is undefined.
  Specified by:
    `getAttributePSVI` in interface `org.apache.xerces.xs.PSVIProvider`
  Following copied from interface: `org.apache.xerces.xs.PSVIProvider`
  Parameters:
    `index` - The attribute index.
  Returns:
    The post schema validation properties of the attribute.

                                                                     java.lang.String localname)

  Description copied from interface: `org.apache.xerces.xs.PSVIProvider`
  Provides `AttributePSVI` given the namespace name and the local name of an attribute information item in the current element's attribute list. The method must be called by an application while in the scope of the methods which report the start and end of an element at a point where the attribute list is available. For example, for SAX the method must be called while in the scope of the document handler's `startElement` call. If the method is called outside of the specified scope, the return value is undefined.
  Specified by:
    `getAttributePSVIByName` in interface `org.apache.xerces.xs.PSVIProvider`
  Following copied from interface: `org.apache.xerces.xs.PSVIProvider`
  Parameters:
    `uri` - The namespace name of an attribute.
    `localname` - The local name of an attribute.
