Syntax:

<?link [href="uri"] [name0="value0"] [name1="value1"] [name2="value2"]
   [if="..."] [unless="..."]?>

Since 3.6.2

It specifies an element that should be generated inside the <head> element. It is generated after ZK default JavaScript and CSS files. Thus, it can override ZK default CSS. Currently, only HTML-based clients (so-called browsers) support them. Furthermore, HTML <link> is actually generated for each of this declaration.

You can specify whatever attributes you like; it is up to a browser to interpret. ZK only encodes the URI of the href and src attribute (by the use of the encodeURL method of the Executions class). ZK generates all other attributes directly to the client.

Notice that these header directives are effective only for the main ZUL page. In other words, they are ignored if a page is included by another page or servlets. Also, they are ignored if the page is a zhtml file.

1 <?link rel="alternate" type="application/rss+xml" title="RSS feed"
2   href="/rssfeed.php"?>
3 <?link rel="shortcut icon" type="image/x-icon" href="/favicon.ico"?>
4 <?link rel="stylesheet" type="text/css" href="~./zul/css/ext.css.dsp"?>

In addition, you could use Script component to embed JavaScript code. The Script component supports more features such as defer, but it has some memory footprint on the server (since it is a component).
