-- DML objects with identical type but different case can't be used in the same folder

* This is a limitation of the Windows operating system on which we run Mapping Services, due to the fact that mapping objects are kept as separate files on the disk (and not as entries in the database as it happens in Composer for example).
In Windows, the names of the files are case insensitive.

To solve rename one of the variables when doing the import of the container and then update all the occurences in the expressions in which the variables are used.

Note that the name of the variables is case sensitive inside the dml expressions.
