FSM Mobile Element Property Validation Rules

Field Service Management (FSM) Mobile validates a value against the following rules when the relevant properties are configured:

required rejects an empty value. A checkbox is always considered to have a value, so required does not require it to be checked.
min, max, and step validate number, date, datetime, and time. The step base is min when supplied; otherwise it is the type's epoch.
precision limits decimal entry in the Number control and formats the displayed value, but it does not add a stored-value validation rule.
maxlength validates text, textarea, and html.
pattern validates email, password, tel, text, and url.
A select's value is an option object (or an array of them when "multiple": true), not just an option identifier.
