    - #### StylesheetRoot

          public StylesheetRoot(XSLTSchema schema,
                        ErrorListener listener)
                         throws TransformerConfigurationException

      Overrides:
        `isRoot` in class `Stylesheet`
      Returns:
        True since this is the root of the stylesheet tree.

    - #### setSecureProcessing

          public void setSecureProcessing(boolean flag)

      Set the state of the secure processing feature.

    - #### isSecureProcessing

        table of available elements, keyed by qualified names, and with values of the same qualified names.

    - #### getExtensionNamespacesManager

          public ExtensionNamespacesManager getExtensionNamespacesManager()

      Only instantiate an ExtensionNamespacesManager if one is called for (i.e., if the stylesheet contains extension functions and/or elements).

    - #### getExtensions

          public java.util.Vector getExtensions()

      Get the vector of extension namespaces. Used to provide the extensions table access to a list of extension namespaces encountered during composition of a stylesheet.

    - #### newTransformer

          public Transformer newTransformer()

      Create a new transformation context for this Templates object.

      For XSLT, Attribute Value Templates attribute values will be returned unexpanded (since there is no context at this point).

      Specified by:
        `getOutputProperties` in interface `Templates`

This method determines the proper import precedence of all imported stylesheets. It then iterates through all of the elements and properties in the proper order and triggers the individual recompose methods.
      Throws:
        `TransformerException`

    - #### getGlobalImport

          public StylesheetComposed getGlobalImport(int i)

      Parameters:
        `sheet` - The stylesheet which will be located in the global import list.
      Returns:
        The index into the global import list of the given stylesheet, or -1 if it is not found (which should never happen).

    - #### getOutputComposed

          public OutputProperties getOutputComposed()

      Get the combined "xsl:output" property with the properties combined from the included stylesheets. If a xsl:output is not declared in this stylesheet or an included stylesheet, look in the imports. Please note that this returns a reference to the OutputProperties object, not a cloned object, like getOutputProperties does.
      Returns:
        non-null reference to composed output properties object.
      See Also:
        output in XSLT Specification

        **For internal use only**

    - #### getAttributeSetComposed

          public java.util.ArrayList getAttributeSetComposed(QName name)
                                                      throws java.lang.ArrayIndexOutOfBoundsException

      See Also:
        attribute-sets in XSLT Specification

    - #### getDecimalFormatComposed

          public java.text.DecimalFormatSymbols getDecimalFormatComposed(QName name)

      Given a valid element decimal-format name, return the decimalFormatSymbols with that name.

      It is an error to declare either the default decimal-format or a decimal-format with a given name more than once (even with different import precedence), unless it is declared every time with the same value for all attributes (taking into account any default values).

      Which means, as far as I can tell, the decimal-format properties are not additive.

      Parameters:
        `name` - Qualified name of the decimal format to find
      Returns:
        DecimalFormatSymbols object matching the given name or null if name is not found.

    - #### getTemplateComposed

          public ElemTemplate getTemplateComposed(XPathContext xctxt,
