Do we know what BA stands for? Might be worth a followup to expand it to
something that is recognizable.

[jaepark, 2016/08/11 18:09:50]

I'm not sure what BA stands for. I know that CPDFSDK_BAAnnot and
CPDFSDK_XFAWidget inherits CPDFSDK_Annot, and CPDFSDK_Widget inherits
CPDFSDK_BAAnnot. 

Since there are CPDFSDK_BFAnnotHandler and CPDFSDK_XFAAnnotHandler, my best
guess is that BAAnnot is actually supposed to be BFAnnot, where BF stands for
base form or basic form in contrast to XFA (XML Form Architecture), but I'm not
confident.
