There are four methods, called context modes, to compute the Context
ID:
* MSB6, where the Context ID is the value of six most
significant bits of p1,
* LSB6, where the Context ID is the value of six least
significant bits of p1,
* MSB6, where the Context ID is the value of six most
significant bits of p1,
* UTF8, where the Context ID is a complex function of p1, p2,
optimized for text compression, and
* Signed, where Context ID is a complex function of p1, p2,

where the _i subscript denotes the transform_id above. Each T_i is
one of the following 21 elementary transforms:
Identity, OmitLast1, ..., OmitLast9, UppercaseFirst, UppercaseAll,
OmitFirst1, ..., OmitFirst9
Identity, UppercaseFirst, UppercaseAll,
OmitFirst1, ..., OmitFirst9, OmitLast1, ..., OmitLast9
The form of these elementary transforms are as follows:
Identity(word) = word
OmitLastk(word) = the first (length(word) - k) bytes of word, or
empty string if length(word) < k
UppercaseFirst(word) = first UTF-8 character of word upper-cased
UppercaseAll(word) = all UTF-8 characters of word upper-cased
