        Description copied from class: Element
        Gets this element's attribute whose attribute tag is given.

        To peek at an attribute, set the peek argument to true. If the attribute is present, it is returned; otherwise null is returned.

        To create an attribute, set the peek argument to false. If the attribute is absent, a default attribute is created and returned; for attributes with no default, null is returned.

        If validation argument is true, and the validation fails, this method throws.

        Overrides:
        getAttribute in class Element
        Parameters:
        eTag - the tag of the attribute.
        bPeek - whether to peek at the attribute or not.
        bValidate - whether to validate the attribute or not.
        Returns:
        the attribute.

        Overrides:
        getAttributeByName in class Element
        Parameters:
        aAttrName - - the attribute name.

                                  boolean bValidate)
        Description copied from class: Element
        Gets this element's sub element whose element tag is given.

        To return the element, set the returnDefault argument to true. If the element is present, it is returned; otherwise the default element is created and returned.

        To peek at the element, set the peek argument to true. If the element is present, it is returned; otherwise null is returned. When set to true, default properties aren't created, and proto references are not expanded.

        To create the element, set the peek argument to false. If the element is absent, a default element is created and returned.

        If validation argument is true, and the validation fails, this method throws.

        If the occurrence argument is out of range, this method throws.

        Overrides:
        getElement in class Element
        Parameters:
        eTag - the tag of the element to retrieve.
        bPeek - whether to peek at the element, or not.

        bValidate - whether to validate the element, or not.
        Returns:
        the element, or null.
