Conclusion: No it is not.
The 2,3 and fourth line should be:
<xsl:stylesheet xmlns : xsl="
XSLT namespace" version="1.0">
<xsl : param name="sortparam" select="datetime" />
<xsl : output method="html"/>
Where I have inserted a space before and after the : with the smilies.
Final conclusion, if you want to write XML and similar code in your posts, you should turn off smilies permanently.
