It indicates the “schema” that will be used to validate the XML in the indicated Namespace.
If the Namespace is not indicated, then that of the scheme's targetNamespace attribute is taken.
Whatever is indicated in this method has priority over the XML document's schemaLocation attribute (to the extent it exists).
To use this method, you must indicate, in the ValidationType property, that either the validation by scheme or the automatic validation is to be carried out.
