HeaderInfo (zk 10.0.0 API)

java.lang.Object
- org.zkoss.zk.ui.metainfo.HeaderInfo

```
public class HeaderInfo
extends java.lang.Object
```
Represents a header element, such as <?link> and <?meta> directives on the ZUML page. They are usually represented as directives in ZUML. For example, the link and meta directives represent <link> and <meta> HTML tags, respectively.
Notice
- Directives are evaluated before all other tags. Thus, it is not possible to set a value in zscript and then reference it in an attribute of the directive.
- If a page is included by another page with the instant mode (Include.getMode()), the directives will be ignored.
- EL is allowed for every attribute.
- Since 5.0.0, the if and unless attributes are supported.
It is not serializable.
