In the first case, you aren't actually passing a string: you are passing a
tree consisting of a document node and a text node as its child. This is a
much more heavyweight structure than the string which you pass in the second
case, because nodes have identity, base URI, parent pointers, etc.

Subject: [xsl] conditional instruction vs. conditional expression
What are the advantages and disadvantages of passing a string
parameter
via a conditional instruction (XPath 1.0):
<xsl:with-param name="content">
<xsl:if test="mb3e:org_list/mb3e:org_code[(_at_)type='APPR' and
text()='ANSI']">
<xsl:text>*</xsl:text>
</xsl:if>
</xsl:with-param>
vs. via a conditional expression (XPath 2.0):
<xsl:with-param name="content"
select="if (mb3e:org_list/mb3e:org_code[(_at_)type='APPR' and
text()='ANSI'])
then '*'
else ''"/>
Thanks,
