5.3 Missing Sub-components

At the beginning of [Schema Component Details], attention is drawn to the fact that most kinds of schema components have properties which are described therein as having other components, or sets of other components, as values, but that when components are constructed on the basis of their correspondence with element information items in schema documents, such properties usually correspond to QNames, and the QName resolution (Schema Document) of such QNames may fail, resulting in one or more values of or containing absent where a component is mandated.

If at any time during assessment, an element or attribute information item is being valid with respect to a component of any kind any of whose properties has or contains such an absent value, the valid is modified, as following:

• In the case of attribute information items, the effect is as if [c-a1] of [Attribute Locally Valid] had failed;

• In the case of element information items, the effect is as if [c-ea] of [Element Locally Valid (Element)] had failed;

• In the case of element information items, processors may choose to continue assessment: see laxly assessed.

Because of the value specification for [e-validation_attempted] in [Assessment Outcome (Element)], if this situation ever arises, the document as a whole cannot show a [e-validation_attempted] of full.
