RichFaces Page Theme -- Include CSS file?

I'm toying with creating a custom RichFaces page theme per the instructions here. I've run the Maven commands and it creates my initial page template, along with a .xcss file where I'm supposed to place my stylesheet properties. I would like, however, to include several different CSS files in my page theme, rather than define them in one huge file. It would make it much easier if I could include, for example, the 960.css file in its own file so that the CSS code is easier to read and edit.

I notice that the instructions talk about how to reference an image file in the XCSS file by using this tag:

<f:resource f:key="/org/richfaces/docs/renderkit/html/images/img01.gif" />

Is there a similar mechanism for including more than one .xcss file in my page theme? I tried simply using:

<f:resource f:key="/org/richfaces/docs/renderkit/html/css/960.css" />

However, I get an XML parsing error, so I'm clearly doing something wrong. Is there a better way to include multiple CSS files in my page theme project and then reference them 开发者_Python百科in the page theme itself?

For anyone else who is struggling with this problem, it appears as though the <h:styles /> tag (xmlns:h="http://jsf.exadel.com/header") is designed to solve this very problem. Place your .xcss files under your renderkit/html directory in your theme, and then reference them using relative paths. i.e.

<h:styles>css/myothercss.xcss</h:styles>
