@Moesian: I didn't miss anything. Just because it uses the word doesn't mean squat. It says the Codex Zographensis is from Western Bulgaria. With suitability I was referring to whether or not it sourced what you claim, which it doesn't. Again, this isn't an issue of ethnicity. Your saying the Ohrid Literary School was Bulgarian is not needed in this article. Don't make this an issue of whether or not there was a Macedonian ethnicity in the middle ages.
@Laveol: The term is used in a purely geographic sense (being from this or that region, etc.). From the absence of any sources, the term West Bulgarian recension does not appear to be in current use. On the contrary, I would actually like to see term explained.
@Gligan: It doesn't matter what "Macedonian" meant back then, we're discussing modern terminology. A reader may also associate the Bulgarian recension with the modern Bulgarian state or even the Bulgars.
