Become XML Certified Professional with DumpsDeals. true:false; Programs can use this with a style sheet to create output for screen, print, audio, video, Braille, etc. 47. In these cases it is arguable that you can ‘execute’ XML code, by running a processing application like Saxon, which compiles the directives specified in XSLT files into Java bytecode to process XML. RPC has huge pool of protocols which at times make it difficult to work with. It is known as universal language for data on the web because XML documents can be created and used in any language.

XML itself does not replace HTML. The v1.0 specification was accepted by the W3C as a Recommendation on Feb 10, 1998. This markup language specifies the code for formatting, layout and style of data .This markup code is called Tag. An important difference between Remote call procedure and local call is that remote call can fail often and this occurs without the knowledge of the user. In document style web services, we can transport an XML message as part of SOAP request which is not possible in RPC style web service. var iframeParams=[]; Whether root element is required for XML? Most SGML tools now handle XML files well, and provide an option switch between the two standards. It omits all the complex and less-used options of SGML in return for the benefits of being easier to write applications for, easier to understand, and more suited to delivery and interoperability over the Web. However, this only needs to be done once, as the two-part name is universally unique. I have to do an overview of XML for my manager/client/investor/advisor. How can I use XML?
