This commit seems to remove most uses of PathMinOccurrence and PathMaxOccurrence but I don't understand what replaces that. Also if such edits to the Items xml is occurring, then the same edits should effect the ebml_schema_example.xml file.

I don't understand this change and the subsequent ones. If the PathMinOccurrence is not present then it is understood to be 0, so this edit seems to mean that the EBML Header is no longer required.

PathMinOccurrence and PathMaxOccurrence are only use for global elements which \EBML and the following ones are not:

PathMinOccurrence represents the minimum number of element path required between the EBMLFixedParent and the Global Element EBMLElementPath.
PathMaxOccurrence represents the maximum number of element path possible between the EBMLFixedParent and the Global Element EBMLElementPath

I have to rework the global elements path to make this clearer (#326)

Basically, most pathes don't have occurences in them anymore. Only the Global Elements do (for now).

I suggest closing in favor of #331

[robUx4]

No objection although one can be done after the other (there won't be any conflict)

closing in favor of the work completed in #331
