Sorry Vinay this is not opinion it is bug.  I will release my improvements
to accounting community tomorrow, with new types and reports to support
equity, however I just look at the latest sources and all the bugs are all
still there.  Then I thought maybe you meant trunk - but it is exactly the
same??

If you need to ask accounting community opinion on whether a dr is on the
left or right side of a balance sheet then serious questions need asking.
Again if OpenERP genuinely believe that an asset can never have a negative
balance, more questions need asking.
If OpenERP really need to ask opinion if the left side of a balance sheet
total should equal the sum of the amounts above it - c'mon really?
Or whether a liability/equity account should ever be added or subtracted
from the Assets side?  This is the basics.

These were the bugs reported, I never asked you to change types, I just gave
an example from my own module on how we handle the negative balances.  It
was never suggested that OpenERP should add these types.  In fact
specifically it was written

"We use more types than standard but you get the idea.  Assets are their
balance, liability is their balance *-1."
