Developers can specify whatever attributes you like; it is up to the browser to interpret. ZK only evaluates the
unless attributes, and encodes the URI of the href and src attribute (by use of by use of Execution.encodeURL(String)). ZK generates all other attributes directly to the client.
<?script src="/js/foo.js"?> <?script content="var foo = true; if (zk.ie) doSomething();"?> <window title="My App"> My content </window>
As shown above, the attribute value could span multiple lines.
Notice that these header directives are effective only when you visit the page directly. In other words, they are ignored if a page is included by another page (<include>) or servlets. Also, they are ignored if the page is a zhtml file.
