                      against value schema-type     schema-instance

Use validated to validate an SGML or XML document instance against a W3C XML schema. This
      function reads the instance from its input-instance argument, validates it, inserts any
      validation markup errors it finds, and reproduces the modified instance. If you prefer to separate the handling of
      validation errors from the processing of original markup, use w3c.validator
      instead.
      
 In case the document instance specifies its schema using the xsi:schemaLocation or
        xsi:noNamespaceSchemaLocation attribute, you may also need to specify the resolver argument
        to help resolve and compile the schema.
      
 This program validates SGML input against a schema, reporting the validation errors together with
          the original markup errors and parsing the rest of the markup at the same time:
          
import "omxmlschema.xmd" prefixed by w3c. process local w3c.xml-schema-type example-schema set example-schema to w3c.compile-schema at "example-schema.xsd" do sgml-parse document scan file "example-input.sgml" do markup-parse w3c.validated #content against example-schema case-insensitive true output "%c" done done element #implied output "%c"
