Quick query about the GL 3.0 spec

Under deprecated functionality the GL 3.0 spec says:

“Legacy pixel formats - all ALPHA LUMINANCE, LUMINANCE_ALPHA, and
INTENSITY external and internal formats”…

should that be ALPHA comma LUMINANCE? (e.g. GL_ALPHA and GL_LUMINANCE) or does “ALPHA LUMINANCE” mean just those formats with LUMINANCE in the name (e.g. GL_LUMINANCE only)?

I assume there is a comma missing. Everything else wouldn’t make sense. But we are talking about a half-baked spec in general, so be prepared for surprises.
