what exactly are you asking here? the number of specialisations allowed per class? certainly 8 will appear in the levelup screen. do you need more? Your tightest restriction comes in the UI of the character generation screen. If you intend to use this to assign your class you're limited to 6 selectable classes.
in both cases, however, you can use dialogues and scripting to add any number of classes and specialisations to a player. classes are really just hidden abilities that other abilities (talents/spells/skills) require. and you can easily add an ability by sccripting, hence you can easily add a "class" (hidden ability) by scripting.
You should take a look at ABI_base.xls and examine the relationship between the ID of abilities (including the hidden ones) and the prereqability field of other abilities.
