VQ44 recommended footprint

The Xilinx packaging documentation for the VQ44/VQG44 package (document PK0
12, v1.2, dataed 2004-06-18) doesn't contain a recommended PCB footprint. I
n attempting to find such a footprint, Google turned up what appears to be
a copy of a Xilinx web page, apparently no longer available from the Xilinx
web site:

Does Xilinx actually still have this information in an current publication?
In the description of the package footprint in my library I'd like to be a
ble to cite a current Xilinx document.

I just made up my own footprint, a 2-minute job in Protel99 to make from scratch, or 30 seconds to tweak the pad widths, etc. from an existing JEDEC footprint. I usually make the stock pads narrower to resist bridging.
Always make sure you know whether pin 1 is in the corner or center of a row. I've been tripped up by that before.

Finally found the information. It's in Xilinx UG112 "Device Package User's Guide".
