<!-- Hyphen character to be used in the exception list as shortcut for
     <hyphen pre-break="-"/>. Defaults to '-'
<!ELEMENT hyphen-char EMPTY>
<!ATTLIST hyphen-char value CDATA #REQUIRED>

<!-- Default minimun length in characters of hyphenated word fragments

     only for aesthetic purposes, wrong hyphens may be generated if this
     is not accounted for.

<!ATTLIST hyphen-min after CDATA #REQUIRED>

<!-- Character equivalent classes: space separated list of character groups, all
     characters in a group are to be treated equivalent as far as
     the hyphenation algorithm is concerned. The first character in a group
     is the group's equivalent character. Patterns should only contain
     first characters. It also defines word characters, i.e. a word that
     contains characters not present in any of the classes is not hyphenated.
<!ELEMENT classes (#PCDATA)>

<!-- Hyphenation exceptions: space separated list of hyphenated words.
     A hyphen is indicated by the hyphen tag, but you can use the
     hyphen-char defined previously as shortcut. This is in cases
     when the algorithm procedure finds wrong hyphens or you want
     to provide your own hyphenation for some words.
<!ELEMENT exceptions (#PCDATA|hyphen)* >

<!-- The hyphenation patterns, space separated. A pattern is made of 'equivalent'
     characters as described before, between any two word characters a digit
     in the range 0 to 9 may be specified. The absence of a digit is equivalent
     to zero. The '.' character is reserved to indicate begining or ending
     of words. -->
<!ELEMENT patterns (#PCDATA)>

<!-- A "full hyphen" equivalent to TeX's \discretionary
     with pre-break, post-break and no-break attributes.
     To be used in the exceptions list, the hyphen character is not
     automatically added -->
