Category

Required Attribute

[2.0 – Schema] validation

Defines how the value of the copied node will be validated. The validation attribute has four values: strict, lax, preserve, or strip.

validation="strict" means that the XSLT processor looks in all the declared schemas for a node declaration (<xs:attribute> or <xs:element>) with the same name as this node. It is a fatal error if the processor can’t find a matching declaration. Assuming the processor finds the declaration of the attribute or element node, it validates the generated value against its declaration in the schema.

validation="lax" works just like validation="strict", except that no error occurs if the processor can’t find the declaration of the node in any of the declared schemas. In that case, the type annotation of a copied attribute or element is xs:untypedAtomic or xs:untyped, respectively.

The value validation="preserve" means that all the ...
