If the temp-table or ProDataSet already contains an ABL definition, READ-XML( ) verifies the XML Schema specified with the schema-location option, or any schema defined or referenced in the XML against the temp-table or ProDataSet definition. Verification is different from the XML notion of validation. Validation refers to whether or not the XML document conforms to a particular XML Schema. Verification is the ABL-specific process of comparing ABL definitions to XML Schema and determining if they are compatible. If verification fails, the method fails.

You have some control over the verification process. The verify-schema-mode option lets you specify a verification mode, which are described in .
