Clarification regarding PageMarginOriginX/PageMarginOriginY for OneNote 2010 format

Hello!

In MS-ONE the properties PageMarginOriginX/PageMarginOriginY are described in chapters 2.3.59/2.3.60.
These properties affect the rendering of a page.

Now we interpret them as following:

1. If we process TitleNode then we don't use these properties.
2. For any other direct child node of a PageNode we do the following steps:
   childNode.HorizontalOffset -= PageMarginOriginX;
   childNode.VerticalOffset -= PageMarginOriginY;

We have mixed results with this approach.
Some pages are rendered well and there is no meaningful difference between pdf file generated by our library and OneNote app.
But others are not rendered so well: we observe differences in relative positions of the elements.

So it would be great to get clarification regarding how we should apply these properties to evaluate positions of elements on a page.

Sincerely, Alexei.
