Dear list,
How can I obtain, from a given PDDocument, a list of the page label 
ranges that it contains?

Here is an example where I obtain the first PDPageLabelRange. How to 
retrieve the other ones? I realize I can iterate over all pages of the 
document and query for the possible existence of a pageLabelRange at 
each page, but I suspect there must be a more efficient (and simpler) way.

try (PDDocument document = PDDocument.load(…)) {
     assert !document.isEncrypted();
     PDDocumentCatalog catalog = document.getDocumentCatalog();
     PDPageLabels labels = catalog.getPageLabels();
     PDPageLabelRange pageLabelRange = labels.getPageLabelRange(0);
}

Thanks.
Olivier
