PropertyHandle :: KeyToString - Convert internal key to string
The passed key will be converted from the internal key instance format into an ESDF string. As field separator '|' is used. Structure levels are enclosed in '{}'. Normally the key passed is assumed to be structured according to the sort key selected for the property handle or according to the identifying key (when no sort key is defined). It is, however, also possible to pass a valid key name for conversion.
Return value: String object ( NString & )
