CSS extensions for XML Opera 5 uses CSS-like properties to attach information to XML elements that cannot otherwise be represented. Three extension properties have been implemented to allow hyperlinks and images to be included in XML documents. This is particularily handy for plaintext formats with unpredictable position of line break characters, like email messages. XML support Opera 5 can parse and display XML documents. In order to display an XML document, a CSS style sheet should be present.
Authors can attach style sheets to their XML documents through a processing instruction.
All elements will be inline, and all text will be rendered in the same font. XSL and XSLT Opera does not support XSL formatting objects, and neither does it natively support XSLT transformations. XML documents transformed server side will be parsed and displayed by Opera just like any other XML document. For an opinion on client side XSL-FO, see Formatting Objects Considered Harmful . XML namespaces Opera 5 supports XML namespaces .
