From: Fabien Parent <fparent@xxxxxxxxxxxx>
The parser was not keeping enough information to allow a good error reporting.
Source Location information has been added inside a property instance to be
able to precisely tell where an error happened when a property does not match
its constraints as specified inside a schema.
Add as well a routine to print error message using these informations in case
of validation error.
