How to add asynchronous resources?

Question

Is it possible to add ressources in a asynchronous way as the below script tag?

<script src="script.js" async></script> 

Answer

To add resources, you can choose the tag <template:addRessources>

The list of attributes, for a javascript type, are the following ones:

• resources : The list of resources they will be included in the defined order. 
• targetTag : The target tag where the link will be inserted 
• condition : optional HTML browser condition (ex : if > IE 6) 
• insert : If set to true the resource is inserted at the top of the resources list. Otherwise, it is appended to the end. 
• title : An optional title value for this asset (in case of a link). 
• key : key for managing uniqueness of inline type. 
• var : Name of the exported pageContext variable to hold the value specified in the action.
