String patterns

All string patterns are written with UNIX-style regular expressions.

Regular expressions are well-defined through a variety of public sources – such as www.regular-expressions.info – and as such are not discussed in detail.

Note: The reference to www.regular-expressions.info is provided for your convenience only, and IBM® makes no representations or warranties, expressed or implied, regarding any information or materials posted on such Web site.

When using regular expressions, be aware that the patternrefs you set for the presentation are intended to match corresponding patterns in your constraints. This means that you can define groups in your constraints, and then refer to those groups from the presentation setting using the standard $# notation.
