ISSUE-79: Negative guards in DTB - is this another dialect?
Neg Guards
Negative guards in DTB - is this another dialect?
- State:
- CLOSED
- Product:
- DTB
- Raised by:
- Christopher Welty
- Opened on:
- 2008-09-27
- Description:
- Negative guards in BLD introduce negation into the language. Jos has demonstrated through several test cases that this allows contradictions and unsatisfiability. Should we move negative guards out of BLD and make it a simple extension?

[ChrisW]: Negative guards
25 Nov 2008, 16:56:56At the Jan. 6, 2009 telecon, the WG resolved to close this issue by restricting the definition of negative guards to return false for all non-literals, e.g. IsLiteralNotOfType(integer, ex:a) returns false, because ex:a is not a literal. See http://www.w3.org/2009/01/06-rif-irc#T16-52-45 (late pointer, scan upwards).
