Description

User community requests ability to add XML comments to elements based on schema annotations.

Also processing instructions similarly. This allows ascribing validation or other errors to parts of a specification such as an Inspection/Sanitization Guide for data.

Note that a feature is present to add Processing instructions that contain a dump of what is called the node-cache of computed property values - this is for debugging purposes but does show how to add PI to a node so it illustrates part of what is needed for this new feature.
