Adobe to Release PDF for Industry Standardization

"Adobe Systems Incorporated (Nasdaq:ADBE) today announced that it intends to release the full Portable Document Format (PDF) 1.7 specification to AIIM, the Enterprise Content Management Association, for the purpose of publication by the International Organization for Standardization (ISO)."

As pointed out at TechCrunch this appears to be in part to attract more government users. I imagine it is also a step to thwart competing doc formats from Microsoft.
