Here is a gendb syntax constraint on parent (and path?):

>From the gendb.cc source code the followingg constraints MUST be obeyed:

DO NOT INSERT ANY SPACES within this statement (anywhere).

Reason:

gendb's parser looks for "parent(".Therefore, 
 "parent (" results in an error during schema parsing.

After parent( is recognzed, gendb copies every byte between "(" and ",",
between two "," separators, and between "," amd ")" into argument strings.
Although the integers may be corrected by atoi or its equivalent (
I didn't check), the Table and field names will cause runtime errors 
when used if a leading or trailing blank is stored inside them 
(failure to match a table or field name reference).

The same constrain may apply to the path statement (I didn't check).
