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
<Part> tag must be changed into the
<Document> tag, see “Create and modify PDF tags in Acrobat”.
