Well X3DJSAIL applies Object Model for X3D (OM4X3D) to Java.  W3C Document Object Model (DOM) has been applied to JavaScript, Java and other programming languages.  Vive la difference.

OM4X3D is getting us much farther down that road.  So does validation in all its many forms: XML, JSON, regexes, etc. etc.

Many of the X3D design patterns are sharable/adaptable.  Learning and "best practices" are always good.

There won't be One Declarative Imperative Programming Content Model That Rules Them All And In The Darkness Binds Them.  :0

SAX is simply a sequential API for reading an XML tree.  Different style, different model.
