It's true that you can transform EDI and GEDCOM files directly into
relational format. I think the reason XML is commonly used as an
intermediate format is that XML is perfect for hierarchical data and you can
leverage a high-performance XML import utility like SQLXML without writing
additional code. Although it will take a while, I expect XML will
eventually replace both EDI and GEDCOM formats. You'll be a step ahead if
you can process XML too.

Hope this helps.
