Change or insert attributes
Elements have attributes that you can edit.
If an attribute is grayed out, it is not available for editing. For example, system attributes – such as class – cannot be edited. Others, such as the conditional attributes (audience, platform, and product), may also be set through their own dialog, which is available from the right-click menu in the XMetaL Editor.
Note: Once you have placed your cursor in an element, you can view or set attributes for any of its direct ancestors up to the topic level by selecting one from the drop-down list at the top of the Attribute Inspector.
