Sorry to bother you the day before Christmas about this tiny issue.
I hope you are all in good health

In DvQuantified class is a little but disturbing error:

**less_than** *alias* "<" (
other: `DV_QUANTIFIED[1]`
): `Boolean`

I thinkt the Post result contradicts with the description
- *Post_result*: `Result = magnitude < other.magnitude` 
- True if `other` is less than this Quantified object. Based on comparison of `magnitude`.

Please have a look at that when you have time.

Enjoy your holidays
Best Regards

Bert,
good catch. I have no idea how that error got in there - it was in more than one class. I think I got them all. There is now a CR (in your name ;) - [SPECRM-101](https://openehr.atlassian.net/browse/SPECRM-101). Feel free to review and update anything if I have made an error. The [changes are visible here](https://specifications.openehr.org/releases/RM/latest/data_types.html#_dv_quantified_class). The sense of the comparison signs in the `less_than()` post-conditions in DV_DATE, DV_TIME and DV_DATE_TIME were also wrong.

Thanks, Thomas, it sounds like a minor thing, but sometimes this can be confusing if it is not well defined which object should be smaller.

So, I am happy that you repaired it, and having my name to it, well, I sometimes need a bit of marketing :-)

Best regards
Bert
