I'd use this string for the signature:
<Signature count="1">%!PS-Adobe-3.1\x20EPSF</Signature>

Ok, I opened an eps file with a hex editor. Here are the first bytes:

Sooooooo, is any of this info helpful for the file sigs, etc?

For instance, the apple file signature for an eps file is

EPSF????

Do I just convert that to hex: 45:50:53:46:3f:3f:3f:3f

and use that?

If so, what is the offset?

I'd like to make a filetypelist for Adobe Illustrator files (.ai) and EPS (encapsulated PostScript) files (.eps)

I have figured out the basic .xml file, but have no idea what to put for the signatures.

Where does one get that information?

TIA
