[BUG] Example for Reference wrong

[BirgitBoss]

Describe the bug
Note

Note: "(SubmodelElementCollection)0, (MultiLanguageProperty)Title" may be identical to "(SubmodelElementCollection)Manual, (MultiLanguageProperty)Title" semantically and content-wise. The difference is that more than one document is allowed in the first submodels and thus a submodel element list is defined: elements in a list are numbered. However, it is also possible to define a display name in this case. The display name of the SubmodelElementCollection should be the same in both bases, e.g. "Users Manual".

is not correct since a number "0" is not allowed as value for idShort

Needs to SubmodelElementList in the first refence. Proposal to remove the hint with the display name since we probably will allow idShort also for Lists.
