Validation of conditional policy attachments

A non-transitory computer-readable medium having stored thereon program code executable by a computer system, the program code comprising:

• code that causes the computer system to generate a runtime policy set for a web service endpoint, the runtime policy set identifying a list of all web service policies that can be attached to the web service endpoint and, for each web service policy, a corresponding constraint expression;
• code that causes the computer system to aggregate the web service policies included in the runtime policy set into a set of groups, the aggregating being performed by constraint expression;
• code that causes the computer system to identify one or more groups in the set of groups that will be simultaneously attached to the web service endpoint at runtime;
• and
• code that causes the computer system to apply one or more validation rules to the web service policies in the one or more groups.

A system comprising:

• a processor configured to:
• generate a runtime policy set for a web service endpoint, the runtime policy set identifying a list of all web service policies that can be attached to the web service endpoint and, for each web service policy, a corresponding constraint expression;
• aggregate the web service policies included in the runtime policy set into a set of groups, the aggregating being performed by constraint expression;
• identify one or more groups in the set of groups that will be simultaneously attached to the web service endpoint at runtime;
• and
• apply one or more validation rules to the web service policies in the one or more groups.
