Implement the ditavalref element in ditamaps to "automate" filtering

FrameMaker 16.0.2

DITA 1.3

I have several ditamaps that share content. The content is tagged appropriately.

When I use the method of Publish > Choose ditaval file > PDF, everything works like a charm. My team would like to include the link to the ditaval file using ditavalref.

So far, my experience is that 1) the filtering doesn't happen and 2) FM inserts content that breaks the structure.

If I remove the broken bits from the structure, the PDF generates but does not filter.

Any suggestions?

Thanks,

Wanda
