The only font specification in my stylesheet is font-family: normal;. Everything is very basic, as I wanted readers to be able to have as much control as their devices would allow.
It just doesn't make any sense to me that the idpf.org validator would take exception to my stylesheet and demand a fallback for an unspecified attribute. I get the error message above for every XHTML page in my ePub file. If the validator gave me a hint of what it wanted a fallback for it wouldn't be so frustrating.
I've attached a copy of the stylesheet as an XML file.
Thanks for your help.

I didn't see any bad in your stylesheet; but it must be named as "stylesheet.css" and not "stylesheet.xml". Change its name in Sigil and after that
link all your xhtml files with that stylesheet. Do that and I think your troubles will be over.
