use css class for multi-line header

I have 4-lines header in a grid and each line should have different styles. Is it possible to use css classes for multi-line headers? Is there a way to do it in XML, so instead of writing

<call command="attachHeader">
	<param>Line1.1, Line1.2, Line1.3</param>
	<param>color:blue; font-style:italic;, color:blue; font-style:italic;, color:blue; font-style:italic;</param>
</call>
<call command="attachHeader">
	<param>Line2.1, Line2.2, Line2.3</param>
	...

To have something like:

<style>
.line1 {
	color:blue;
	font-style:italic;
	}
...
</style>
<call command="attachHeader">
	<param>Line1.1, Line1.2, Line1.3</param>
	<param>line1, line1,line1</param>
</call>
...

Unfortunately such feature is not available. We may only suggest you to add html elements as a titles of your column with the needed class name.
For example:

[code]

<![CDATA[
Line1.1
,
Line1.2
,
Line1.3
]]> [/code]
