revXMLText not formatting output?

[webmaster at curiositi.com]

Has anyone had success using revXMLText to output a formatted XML file 
from an XML Tree?  The dictionary says the last parameter should control 
this feature.

 From the dictionary:

revXMLText(treeID [,startNode] [, formatted])
[...]
formatted - Whether or not to produce xml with indenting and line 
breaks, i.e. "pretty-printed". If you don't specify a formatted value, 
the default is not to format the text, this will  result in the xml 
being output as a single block with no line breaks.

Here are the commands I am using:

open file tCurrFolderPath & "/element.xml" for write
write revXMLText(tTreeID, ,true) to file tCurrFolderPath & 
"/element.xml"
close file tCurrFolderPath & "/element.xml"

The resulting file does not have indenting and line breaks.  Should I 
be entering a different value for the formatted parameter?
