Missing clear explanation about where to set the "aspect" annotation in order to enable the trace manager and omniscient debugger

There is no documentation about how and where the language designer should place the "aspect" EAnnotation in order to define the runtime data.

Should the annotation be put on the EAttributes, EReferences, EClasses? Does some of them is enough or should the language designer tag all the structure? (for example does tagging an EClass is enough and so we don't have to tag its Eattributes ?)

This job is partly done when using melange but there is no direction about doing it manually. (

This is quite important since missing to tag some concept may lead to errors such as those in #85
