Ups, thanks for all the answers! This is the the only mailinglist i
know where you get replies in a nanosecond. ;-) Now i will chum up
with the xsl:text element. Also i will try to replace my xsl:.if
statements with the method mentioned by andrew. I think this will make
my scripts much smaller.

Whitespace only text nodes get dropped by default - that means any
text node consisting soley of whitespace (like the whitespace used to
indent your XSLT).
So with that in mind, use <xsl:text> </xsl:text> or <xsl:value-of
select="concat(Firstname, ' ', Lastname)"/>

Here the text node contains a '(' so it doesn't get dropped, and the
text node consists of the carriage return and indetation that you've
used to indent your code - which is what your are seeing in your
output. To avoid this write all the code inline, or use concat.
Also, rather than use xsl:test="exists(...)" just use apply-templates,
as then if the element exists it will be processed, otherwise it wont:
<person>
<xsl:apply-templates/>
</person>
<xsl:template match="mds:node17">
<name>
<xsl:value-of select="."/>
<xsl:apply-templates/>
</name>
</xsl:template>
<xsl:template match="mds:node18">
<xsl:value-of select="concat('(', node18, ')'"/>
<xsl:template>
