Yes, I get your point. OTOH in TDG there is written (in reference page 
for imagedata):

"Lengths must be expressed as a decimal value followed immediately by an 
optional unit of measure or a percentage."

So the question is how closely grammar should follow DocBook 
specification. More restrictive grammar can be to restrictive for some 
users but also can catch some errors that will break processing 
toolchain later.
