Like the title says, I'm trying to determine if data is a standard attribute in the XHTML strict doctype. I can't seem to find any information online (looks like its HTML-5ish).

If you're talking about attributes with the data- prefix, that's indeed HTML5 only. If you want to use them in XHTML, you'd need XHTML5.
There is also an attribute whose name is just data. It's for <object> elements and works like the src attribute on images. It's part of HTML4 and XHTML1 in both Strict and Transitional doctypes.
