ISSUE-19
Advice against using the 'all' model group
- State:
- CLOSED
- Product:
- Advanced
- Raised by:
- Paul Downey
- Opened on:
- 2006-02-21
- Description:
The input document advises for a collection: """ The all model group may appear attractive given programming language techniques such as introspection or reflection often return items in a random order. However, there are significant restrictions placed upon all types, not least an element cannot have a maxOccurs value greater than 1. The Unique Particle Attribution (UPA) constraint prevents a model group of all from being extended, either by containing an any element wildcard, being incorporated in a substitution group or derived using extension or restriction. """ Should we carry this advice into our Basic Patterns?
