Help initial-property-set

[Roberta]

Hi all,
I'm using XEP and I have this problem.
I want the first line of a text to have an end indentation. So I tried to
use:

<fo:block>
<fo:initial-property-set padding-right="2mm"/>
<xsl:value-of select="MYTEXT"/>
</fo:block>

The problem is: if I try the above code using a constant text, it works. So:

<fo:block>
<fo:initial-property-set padding-right="2mm"/>
This is my sample text
</fo:block>

works, but using <xsl:value-of...> has no effect!

Can anyone help me?

Thanks a lot
Roberta
