It's been a few days since I last looked at this PR.

Please remind me, with the current implementation, how is the per-field-configuration made, to set whether it is a date-and-time-field or just a date-field?

[Antoniafriedrich]

In editor-includes.xed, you can configure two attributes to control the behavior of date fields:

showDateTimeOption: Set this to true to include the time option in date fields. This mainly influences whether you can choose this option if you have a dropdown with many options such as Date, Daterange and Datetime.

startsWithDateTime: Set this to true to make the date-time option the default when the page with the date field is loaded.

These attributes can be added to the textfields of templates inside editor-includes.xed. If these attributes are left empty or set to false, the standard behavior of the date fields remains unchanged.
It should be possible to create a new template with these attributes and add it to your MyCoReWebPage.

The logic for that is mostly handled in mir2xeditor.

I have added the attributes as an example in one template, set to false, so the behavior should not change unless changed to true.

Edit: Meant mir:dateRange and not mir:textfield. Sorry about that miscommunication.

I've noticed a potential problem (see comments).

I've also tried out your PR extensively with my application and an unmodified MIR (current version of MyCoRe- and MIR-main-branch respectively) and was so far unable to even see the UI for entering a time value, let alone check, if everything works consistently.

Please demonstrate the feature during the next web conference, or guide me through using is.
