Documentation: Date Field

After much searching and testing, I've finally made some headway creating rules based around the datefield. Since there's a lot of issues related to using date within Rules, I'd like to submit documentation to help out, but wasn't sure if I should post here first or just dive straight into the Docs page.

The biggest issue that should be addressed in documentation is that it is impossible to get a custom date-time format as set in configuration (ie, I had one called "Year" that only displayed a datefield's year) if trying to interact with the field directly through the data selector: it is only available through direct input mode.

For my specific usecase, I wanted to set an integer field with the year of a full datefield. I originally tried to set this variable as a "date," then convert it to an integer, but was again unable to get the custom date-field format I wanted. I had to use a text variable with direct input mode, which allowed selection of the year formatter ([term:field-origin:value:year]). I could then convert it to an integer, and set the data as such.

Also: setting another field with the value of a datefield's end date is confusing; if no enddate is set, Rules will assume the startdate is the enddate and use that value to set the next field as required by the Rule. The only way I could avoid this issue was by adding a condition comparing the first and second field values, Negating the Equals comparison to ensure that the Rule realized it was looking for a different value.

I'd be glad to craft a documentation page with screenshots to help based on some of my examples, but am unsure where to put them.
