However, most of the elements and attributes are things you dont need. And you know the full schema will blow out implementatuon and confuse testing and anyway YAGNI. 

So you will make profile (Subset) of it using restriction and distribute that. 

But then your schema documents may be bloated. It may be simple just have a parallel validation which just check that only wanted element names are used, using any schema language. 

I.e. In allow elements a,b,c,d,e,f,g,... only chill elements a,b,c,d,e,f,g,... can be used. So the big schema states all the rules. The small one excludes unwanted canes, making it really expect. The trouble with restriction is not knowing exactly what the differences are or why.
