I accomplished this in 1.9 CE by adding the following code to local.xml within the layout folder of my theme (you can create the file if it is not there already):
<layout version="0.1.0">
<catalog_product_view>
<reference name="product.info">
<block type="catalog/product_view_description" name="product.models" as="models" template="catalog/product/view/models.phtml">
<action method="addToParentGroup"><group>detailed_info</group></action>
<action method="setTitle" translate="value"><value>Models Supported</value> </action>
</block>
</reference>
</catalog_product_view>
</layout>
and adding the following file to magentoroot/app/design/frontend/themepackage/themename/template/catalog/product/view/models.phtml
<?php $ingredients = $this->getProduct()->getData('model_support');
echo $ingredients;
?>
In this case 'model_support' represents the particular attribute I have chosen to display, you must reference a relevant attribute within your store. Also verify that the attribute properties is set to yes, Visible on Product View Page on Front-end.
Also I wanted to prevent the Additional Data tab from displaying, so I also added the following code:
<reference name="product.info.tabs">
<action method="unsetChild">
<child>product_additional_data</child>
</action>
</reference>
Note: you will need to update your paths to use the relevant paths for EE and your theme configuration
