Thanks for making that last part clear. I have come across a few "unanswered" questions that had all(?) the answers posted via comments. I thought it would be poor etiquette to create an answer based on other people's comments.

Thanks for showing the way. @Bart : Care to turn your comment into an answer? I accept "consider replacing [pci] with [pci-bus], and edit PCI DSS questions so that they reference [pci-dss] instead of [pci]".

I do mean SO here. I search for questions related to programming PCI(e) BARs, and keep getting hits for PHP / PCI (DSS).
