Summary:

     This DTD fragment exactly duplicates, with some reorganization,
     correction, and reformatting of the descriptive text, the 253
     character entity declarations in the XHTML 1.1 DTD. Refer to:

          http://www.w3.org/TR/xhtml1/DTD/xhtml-lat1.ent
          http://www.w3.org/TR/xhtml1/DTD/xhtml-symbol.ent
          http://www.w3.org/TR/xhtml1/DTD/xhtml-special.ent


Relation to OEBPS Version 1.0.1:

     The 253 character entities declared herein include all 249 from
     Version 1.0.1 plus four of the five pre-defined XML 1.0 character
     entities of &amp;, &lt;, &gt;, &quot; (the fifth pre-defined XML
     character entity, &apos;, is one of the 249 character entities
     already declared in Version 1.0.1.)

     The five pre-defined XML 1.0 character entities are included for
     completeness and interoperability as recommended by W3C, and to
     follow XHTML practice. (Further information on the purpose and
     usage of these five pre-defined XML character entities, and the
     normative reference, is given in the Usage Note below.)


Relation to Unicode 3.2.0 and ISO/IEC 10646:

     The mnemonic character entities declared herein substitute for
     numeric character references, the numeric values for the
     associated characters specified by Unicode (in turn, the Unicode
     Character Data Set conforms with the ISO/IEC 10646 character set
     which XML 1.0 specifies.) The current version of Unicode is
     3.2.0. General information on Unicode, including information on
     the latest version, is found at

          http://www.unicode.org/

     In addition, Unicode has categorized the massive number of
     characters in its Character Database using two different systems:
     Character Blocks and Script Names. These two systems are used
     herein for general categorization of the 253 character entities.
     The text files listing the code points for these two systems are:

Tutorial Note to Document Authors: Character Entity Usage

     To insert the desired special character into the content of an
     OEBPS Document or Package file (which are XML documents), prefix
     the associated mnemonic character entity with the '&' character
     and terminate with the ';' character.

     Example: to insert the "em dash" character (which has the
     mnemonic 'mdash'), use &mdash; .

     If preferred, the character can instead be inserted using the
     direct (Unicode) numerical character reference, the codes of
     which are given herein (see the above note on Unicode.) So, for
     the "em dash" character one can use, instead of &mdash;, either
     the decimal &#8212; or the hexadecimal equivalent &#x2014; .

     Importantly note that within the content (PCDATA) of all OEBPS
     documents and package files, the special XML characters '&' and
     '<', when intended to be used literally, MUST be represented with
     the mnemonic character entities of &amp; and &lt; (or the numerical
     character entity equivalents), respectively. In addition, it is
     considered good practice to use the &gt; (or numerical equivalent)
     for the '>' symbol, although it is not necessary except in very
     unusual and rare circumstances. The two other special XML character
     entities, apostrophe (&apos;) and quote (&quot;), are only
     necessary within element attribute values to literally represent
     these characters, and for similar non-content purposes.

     (The normative reference on the five XML pre-defined mnemonic
     character entities is given in Sections 2.4 and 4.6 of the XML
     1.0 Specification, Second Edition:

          http://www.w3.org/TR/2000/REC-xml-20001006

                Script Name(s):  (none)

           Note: The Spacing Modifier Letters are an unusual class of
                 characters. They are an assorted collection of small signs
                 used to indicate modifications of the preceding or
                 following character, and sometimes to be an independent
                 character. They differ from diacritical marks in that they
                 are treated as free-standing, independent characters, which
                 form part of the word and do not break up the word. They
                 have the "letter" property. Most of the characters are
                 phonetic modifiers. For further information, refer to
                 Section 7.8 of the Unicode 3.2 manual, an online version is
