Re: Following-Sibling

Using the following-sibling format above, it seems to put the processing
instruction in to every paragraph.  If you have any ideas or suggestions,
I'd really appreciate it.

Every para in your sample XML has a note element on the following
sibling axis, therefore the node set following-sibling::note has
always a member and the predicate is always true. You want to match
only para elements where the immediately following element is a
note element (note the different formulation). This translates to
  <xsl:template match="para[following-sibling::*[1][self::note]]">
(I hope)
BTW a leading // in a match pattern is redundant for all practical
purposes.
