Document isn’t the top-level tag
A PDF converted from Word contains the <Part> element as its top container. However, the semantically more suitable <Document> tag should be used as root element.
Issue detected in PDFs made from: #
- Microsoft Word 2013 for Windows
PAC 3 warning #
“Part” structure element used as root element
Failure Condition of the Matterhorn Protocol #
01-006 The structure type and attributes of a structure element are not semantically appropriate for the structure element. All of the existing structure types must be taken into account. (→ manual testing)
Manual approach in Acrobat #
The topmost <Part> tag must be changed into the <Document> tag, see “Create and modify PDF tags in Acrobat”.
