IE5.0 and XSL

I have tried the final release of IE5.0 and it seems that it doesn't
support at least the following tags:

<xsl:sort
<xsl:text

I have an XML document with a link to an XSL document, IE5 told me that
these tags (sort and text were unknown ??) so after removing them, I
reloaded my XMl document and  I had a pretty blank page ?? Where are all
my data output by <xsl:value of are ???
I do have the right html tags  and headers in my stylesheet.
It is working fine with lotusxsl

If somebody has a clue... Anyway if it doesn't work, I will zap IE5 from
my HD....
