XmlPL - Implicit Type Coercion

The table below lists XmlPL's implicit type conversions. Entries represent casts from the type in the left-most column, the from type to the type in the top-most row, the to type.

If the table entry is false then a cast from the from type to the to type is not allowed. If a true value or another type name is present then an implicit type coercion will be performed by the compiler. If another type is listed this indicates that the implicit type coercion will be performed in more than one step.

Some type names in the table are abbreviated. Their translations are listed below.
