The former technique will cause parsers to use the new validation API; the latter will cause parsers to use their own internal validation facilities.
In this case Java serves me well as it can run on Windows and Unix platforms meaning I can use the same validator for the frontend and backend validation.
lv_valdator_type = 'ZCL_EVP_XML_VALIDATOR_BE'.endif.create object lo_validator type (lv_valdator_type)....

In this page you can check the validity of your XML Schema (XSD) file. The library used in this page is jaxp, Java API for XML Processing, version 1.4, from Java(TM) SE Runtime Environment (build 1.7.0_06-b24).

An XSD Schema is used to validate an XML document, it describes what elements, attributes, types are allowed and in which order.
Where the DOM reads the whole document to operate on XML, SAX parsers read XML node by node, issuing parsing events while making a step through the input stream. On the other hand, DOM is easier to use and there are tasks, such as sorting elements, rearranging elements or looking up elements, that are faster with DOM.
SAX processes documents state-independently (the handling of an element does not depend on the elements that came before). A SAX parser comes with JDK, so there is no need to dowload a dependency.

In this tutorial, we have read and validated an XML document with Java SAX.
XSD files are "XML Schemas" that describe the structure of a XML document.
