HeadingLine in TitlePageZone ?

[malamatenia]

A thorny question ahead :
Is there a differentiation between the content inside the TitlePageZone (or should be made for the Title per se)?
Since the page contains the metadata for the document in question, would it be useful to explicitly state where the title is and differentiate it from the rest of the information (that varies as per the document)? Does this play a role in the extraction of the information later on?

*attaching two examples, one presenting a rich and one a rather minimal TitlePageZone

Merci!
