    Methods
    Modifier and Type | Method and Description
    --- | ---
    `ElemTemplateElement` | `appendChild(ElemTemplateElement newChild)` Add a child to the child list.
    `void` | `compose(StylesheetRoot sroot)` This function is called after everything else has been recomposed, and allows the template to set remaining values that may be based on some other property that depends on recomposition.
    `void` | `execute(TransformerImpl transformer)` Create a processing instruction in the result tree.
    `AVT` | `getName()` Get the "name" attribute.
    `java.lang.String` | `getNodeName()` Return the node name.
    `int` | `getXSLToken()` Get an int constant identifying the type of element.
    `void` | `setName(AVT v)` Set the "name" attribute.
