 to do:
 texttable
  (can we do the "every count(ttcol) c's is a row" thing?)
  (probably needs java help)
 <?rfc include= -- editable attribute
 list: can we inherit style from the closest parent as specified?
 additional validation: can we enforce things like the structure
  of the postal?
 Do any of the xpath() rendering bits need to be label()s?
