- - ddl_transform_input(ddl, input) - -

- -

-

-For an input where the DDL requests a boolean or -some number this will convert the input to the right type where possible -else just returns the origin input unedited -

-

-if anything here goes wrong just return the input value this is not really -the end of the world or anything since all that will happen is that DDL validation will fail and the user will get an -error, no need to be too defensive here -
