We could also say that specifying only one coordinate has no effect. I think the requirement that both attributes have to be present or absent cannot be specified in a document type definition (if someone would like to have one nevertheless).

I still don't understand why the spec has to define each and every parser algorythm (IMO, it should only define the syntax, and then the implementation should define its own algorythm that parses that syntax as defined); but if that's the issue then a microsyntax can be perfectly avoided by splitting the argument into two separate ones, such as pixelratiox and pixelratioy. The only issue I have with splitting it into separate ones, is that we need to ensure that both exist or none exist, having just X or just Y is clearly confusing and should not be allowed. -- Sander
