<!-- smilCustomTest - Duplicates customTest data found in SMIL files. Each unique customTest element that appears in one or more SMIL files must have its attributes duplicated in a smilCustomTest element in the NCX. The NCX thus gathers in one place all customTest elements used in the SMIL files, for presentation to the user.

<!-- Navigation Point - contains description(s) of target, as well as a pointer to entire content of target.
Hierarchy is represented by nesting navPoints. "class" attribute describes the kind of structural unit this object represents (e.g., "chapter", "section"). "value" attribute is a numerical representation of the text content of the
label if this is a purely numerical (integer only) label (e.g., a page number). "pageRef" is the id of the page navTarget on which this structure target begins.
<!-- Navigation List - container for distinct, flat sets of navigable elements, e.g. page numbers,
notes, figures, tables, etc. Essentially a flat version of navMap. The "class" attribute describes the type of object contained in this navList, using dtbook element names, e.g., pagenum, note.

<!-- Navigation Target - contains description(s) of target, as well as a pointer to entire content of target.
navTargets are the equivalent of navPoints for use in navLists. "mapRef" is the id of another navPoint within this NCX that contains this navTarget. "class" attribute describes the kind of structure this target represents, using its dtbook element name, e.g., pagenum, note.

<!-- Navigation Label - Contains a description of a given <navMap>, <navPoint>, <navList>, or <navTarget> in various media for presentation to the user. Can be repeated so descriptions can be provided in multiple languages. -->
