xtree Behavior Changes - Caveat

In (syntax) version 8 and later, <xtree> has some behavior changes:

  • $ret.count/$ret.seq are always set, even when non-looping

  • Some actions (e.g. SET/GET) cannot be performed in the looping syntax

  • Looping syntax is determined by lack of self-close tag (as noted above for all loopable statements, here)
