No; if developers on those platforms want to support optional 
platform-specific performance boosting, they should define 
platform-specific names for the attribute.  This improves the ease of 
portability for applications: they just provide what they know how to 
provide, and the server only invokes the attribute appropriate to the 
platform, if it invokes any attribute at all.
