Well, you can use another TS-hack. ;)

page {
    20 = COA
    20 {
      50 < styles.content.get
      50.stdWrap.ifEmpty = <h2>testme</h2>
      wrap = <div id="content">|</div>
    }
}

The only problem is that 'ifEmpty ' returns false if you have applied
some wrap on the same TS-object. That's why you need that extra COA around.

IMO this should go into a register, if its not there already, shouldn't it?

Groetjes,
Peter
