71 
72  the rules of priorities that govern the addition of kashidas in Arabic text
73  made ... for ... Explorer 5.5 browser.
74 
75  The kashida justification is based on a connection priority scheme that
76  decides where kashidas are put automatically.
77 
78  This is how the software decides on kashida-inserting priorities:
79  1. First it looks for characters with the highest priority in each word,
80  which means kashida-extensions will only been used in one position in each
81  word. Not more.
82  2. The kashida will be connected to the character with the highest priority.
83  3. If kashida connection opportunities are found with an equal level of
84  priority in one word, the kashida will be placed towards the end of the
85  word.
86 
87  The priority list of characters and the positioning is as follows:
88  1. after a kashida that is manually placed in the text by the user,
89  2. after a Seen or Sad (initial and medial form),
90  3. before the final form of Taa Marbutah, Haa, Dal,
91  4. before the final form of Alef, Tah Lam, Kaf and Gaf,
92  5. before the preceding medial Baa of Ra, Ya and Alef Maqsurah,
93  6. before the final form of Waw, Ain, Qaf and Fa,
94  7. before the final form of other characters that can be connected.
