Core Schematron Rules (CSR)

The following rules are defined in the base core schematrons ( errors, warnings and infos).

Rule ID: II

Extends Rule(s): ANY

Level	Constraints	ID
	@root is required if @nullFlavor is not present	dtr1‑1‑II
	@root may not be used if @nullFlavor is present	dtr1‑2‑II
	@identifierName may not be used if @nullFlavor is present	dtr1‑4‑II
	@displayable may not be used if @nullFlavor is present	dtr1‑5‑II
	@reliability may not be used if @nullFlavor is present	dtr1‑6‑II
	@assigningAuthorityName may not be used if @nullFlavor is present	dtr1‑7‑II
	@root should not be longer than 128 characters. Found string-length(@root) characters. Please write a note to the authors of this rule if this is found to be not sufficient	dtr1‑8‑II
