Logical Reading Order - Needs a Manual Check

Verify this rule check manually. Make sure that the reading order displayed in the Tags panel coincides with the logical reading order of the document. 

1. First verify the headings structure -- is this the order you intended for your audience?
2. Then check the whole document's reading order to make sure the objects (such as the headings, the paragraph texts, images, and such) are organized in a logical order.
