PDF/A and PDF/UA formats impose a number of accessibility requirements related to document content that cannot be fulfilled during automatic conversion from Word to PDF. These requirements are described in the previous article “Working with PDF/A or PDF/UA”. Now warnings are issued for some of these problems.
Warnings are issued when saving to one of the PDF/A or PDF/UA formats and the issue violates compliance. For example, the warning about missing document title will be issued when saving to PDF/UA and will not be issued when saving to PDF/A.
All warnings are of WarningType.MinorFormattingLoss and WarningSource.Pdf. Here is a list of the new Description warning values:
