Maybe I am too simplistic here, but it seems that everybody in this
discussion is assuming that the values have to be numeric and hence we have
to a x-value and a y-value.
Why not stay with a simple approach of using ASCII text strings, and just
define ONE attribute with the value for the attribute being a simple text
string allowing values like:
"300x300"
"300x600"
"600x600" etc
with an additional rule that what comes before the "x" is the x-value and
what comes after it is the y-value.
This could also allow for cases like:
"300"
which would be semantically equivalent to:
"300x300"
