Syntax Error.
#3023 Compile-time error or run-time catchable error

Additional Information
Expecting X, but received Y.
or
Expecting a simple pattern, but received a complex pattern.

ul does not apply to the X pattern.
where X is any of the predefined character classes: any, any-text, blank, digit, lc, letter, space, or uc.
or
Can't refer to X outside a repeat over block.
where X is either #item, #first, or #last.
Recovery
Compilation continues but no compiled source code file will be saved.
Explanation
The entered text does not conform to the syntax of the
OmniMark language. These are the most common messages that occur
under this heading, but there are many more in OmniMark that are
presumably self-explanatory.
