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

       Spacing Modifiers

       Drawn From Unicode 3.2.0 Character Sets:



             Block Name(s):  Spacing Modifier Letters (U+0280 to U+02FF)

            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

             at http://www.unicode.org/unicode/uni2book/ch07.pdf .
