Verifying XML Schema against 4GL definitions

If the temp-table or ProDataSet already contains a Progress 4GL 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 Progress-specific process of comparing 4GL 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 Table 22–5.
