[xsl] Including precediing-siblings with the first group

["rick@xxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi All,



I have an input file that I want to split into files at each section. The
first section should include everything before it. Below are my input, desired
output, and stylesheet. I am pretty sure this is the simplest approach, but
any suggestions would be appreciated. Thank you.



Rick
