whitespace is always a stumbling block, but if you look at what you've
written:
<xsl:otherwise>
isn't three
</xsl:otherwise>
You have a CR/LF, some spaces, the chars 'isn't three', and then another
CR/LF... and thats what is making it through into the output. Your
'presentational whitespace' is actually part of your output.
There are three ways to handle literal text:
1. Dont use presentational whitespace (ie no indenting of code)
<xsl:otherwise>isn't three</xsl:otherwise>
2. Use <xsl:text> (all whitespace only nodes are ignored)
<xsl:otherwise>
<xsl:text>isn't three</xsl:text>
</xsl:otherwise>
3. Use a combination:
<xsl:otherwise>isn't three<xsl:text/>
</xsl:otherwise>
Its all down to taste, really.
