Almost identical to the SUPPRESS-NAMESPACE-PROCESSING attribute of the X-document handle. For more information on SUPPRESS-NAMESPACE-PROCESSING, see the reference entry for the SUPPRESS-NAMESPACE-PROCESSING attribute.
What XML-SUPPRESS-NAMESPACE-PROCESSING avoids
In WebSpeed, the first time you access the X-document handle or any of its attributes, either directly or indirectly, you trigger a load of the document, which precedes your access. For example, if you set the SUPPRESS-NAMESPACE-PROCESSING attribute of X-document (of WEB-CONTEXT) before accessing X-document (of WEB-CONTEXT) or any of its attributes, when the document arrives, WebSpeed first loads the document, then sets SUPPRESS-NAMESPACE-PROCESSING to your value. So at load time, SUPPRESS-NAMESPACE-PROCESSING might not be set to your value, which might cause document validation to fail.
By contrast, if you set XML-SUPPRESS-NAMESPACE-PROCESSING instead of SUPPRESS-NAMESPACE-PROCESSING, when the document arrives, WebSpeed assigns the value of XML-SUPPRESS-NAMESPACE-PROCESSING to SUPPRESS-NAMESPACE-PROCESSING before doing anything else. Even if this triggers a load of the document, SUPPRESS-NAMESPACE-PROCESSING already contains your value, so WebSpeed is able to validate your document.
How to use XML-SUPPRESS-NAMESPACE-PROCESSING
In WebSpeed, instead of accessing SUPPRESS-NAMESPACE-PROCESSING of X-document (of WEB-CONTEXT), access XML-SUPPRESS-NAMESPACE-PROCESSING (of WEB-CONTEXT). For example, if you want a WebSpeed application to turn namespace processing off (perhaps in response to a Web request), instead of having the application assign FALSE to SUPPRESS-NAMESPACE-PROCESSING of X-document (of WEB-CONTEXT) have the application assign FALSE to XML-SUPPRESS-NAMESPACE-PROCESSING (of WEB-CONTEXT).
