Since I couldn't get the FOSI to format the PIs, I decided on a different approach. I was able to insert pseudo attributes, such as <?Pub Lcl src-rqrd1="Drawing">, which the FOSI would recognize as attributes on the parent element. I could then use the FOSI on those attributes as long as I included those attributes in the atiattr.cf file.
The issue I am having now is when normalizing some of the FOSIs I am running into the error:
Capacity limit IDREFCAP exceeded. The number of points to add is 288;
the program has already used 299880 points and the declared maximum
value is 300000
Trying to resolve that issue now.
Thanks.
