Syntax:

<?root-attributes any-name1="any-value2" any-name2="any-value2"?>

It specifies the additional attributes for the root element of the generated output, which depends on the device types.

Currently, only Ajax devices support this feature and the root element is the html tag. In other words, the attributes specified in the root-attribute directives will become the attributes of the <html> element of the generated output. For example,

any-name*

any-value = Any numbers of names and values are allowed. The value can contain EL expressions.

Examples

 <?root-attributes xmlns:v="urn:schemas-microsoft-com:vml"?>

will cause the HTML output to be generated with the following snippet

 <html xmlns="[http://www.w3.org/1999/xhtml http://www.w3.org/1999/xhtml]"
 xmlns:v="urn:schemas-microsoft-com:vml">

<?root-attributes lang="EN"?>

Note:

  • xmlns="http://www.w3.org/1999/xhtml" is always generated.
  • If the value is specified with an EL expression, and it is evaluated to null, the corresponding attribute won’t be generated into the target HTML page.
