EXTERNAL-ENTITY rule condition conflict.

#2104   Compile-time error

EXTERNAL-ENTITY rule condition conflict.

Additional Information

An unconditional rule for the external entity 'X' has already been entered, so no other rules are permitted.
    or
Previous rules for the external entity 'X' have conditions, so the current one requires one as well.

Recovery

Compilation continues but no compiled source code file will be saved.

Explanation

It is an error if more than one external-entity rule can be selected at any one time and any particular external entity can appear in either only one rule without a condition or several conditional rules.
