Extension Maximum repetitions - Detailed Descriptions

Detailed Descriptions for the elements in the extension.

Definition

The maximum number of times the group must appear or the minimum number of answers for a question - when greater than 1 and not unlimited.

InvariantsDefined on this element
inv-2: maxOccurs can't be more than one if repeats is false (xpath: f:valueInteger/@value<=1 or parent::*/f:repeats/@value=true())
inv-4: maxOccurs can't exist for display items (xpath: not(parent::*/f:type/@value='display'))

Extension.url
Definition

Source of the definition for the extension code - a logical name or a URL.

Control1..1
Typeuri
Comments

The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition should be version specific. This will ideally be the URI for the Resource Profile defining the extension, with the code for the extension after a #.
