It fixes the collision of column values and footer text, but it caused 
a grave problem for reg_d_individual.xsl and text in other *.xsl files 
to change regressively. For the most grave example:

cd /opt/lmi/data
cp reg_d_individual.xsl illustration_reg.xsl

cd /opt/lmi/bin
./lmi_cli_shared \
  --accept \
  --cnsfile=/opt/lmi/src/lmi/sample.cns \
  --data_path=/opt/lmi/data \
  --emit=emit_pdf_file \
  2>&1 |less

To see the text that's moved to its own page:

cd /opt/lmi/data
cp nasd.xsl illustration_reg.xsl

cd /opt/lmi/bin
./lmi_cli_shared \
  --accept \
  --cnsfile=/opt/lmi/src/lmi/sample.cns \
  --data_path=/opt/lmi/data \
  --emit=emit_pdf_file \
  2>&1 |less

I now see the last two lines of the 'Premium Outlay' definition (it's
located about halfway through the output) are printed as two lonely 
lines on the next page (besides the usual headers and footers). That's 
just one example. I see similar instances in other formats, too.

I also observe the number of rows is not consistently thirty throughout
all pages. I realize that was more of a "nice to have" request, but the 
upgrade doesn't help the inconsistency.

Could you please show me more precisely where I would add that padding?
I can't see the where it belongs in neither 'fo_common.xsl' nor
'nasd.xsl'.
