TL;DR:
Your example should work as long as toObject is not empty object.
This might be more secure:

LOCAL oTableInfo
oTableInfo = CREATEOBJECT("empty")
ADDPROPERTY( oTableInfo, "config_xml", "" )
ADDPROPERTY( toObject, "oTableInfo", oTableInfo)

Long:
This is the syntax for empty object:

LOCAL oTableInfo
oTableInfo = CREATEOBJECT("empty")
ADDPROPERTY( oTableInfo, "config_xml", "" )

This is because the empty object is empty - it exposes no methods or events - so there is no .AddProperty() method and you must use the AddProperty() function.

Any other object works both ways

LOCAL oTableInfo
oTableInfo = CREATEOBJECT("custom")
ADDPROPERTY( oTableInfo, "config_xml", "" )
oTableInfo.AddProperty("SomeProp", vSomeValue)

Conclusio, long code short:

ADDPROPERTY( toObject, "oTableInfo",  CREATEOBJECT("empty") )
ADDPROPERTY( toObject.oTableInfo, "config_xml", "" )
