XSLT 1.0 is capable to handle anything (turing machine).
XSLT 2.0 brings some syntactic sugar.
XSLT 3.0 supports streaming.
 
If you need 2.0 features, you can use Saxon-B 9.1.0.8 (free, but not
maintained any more).

In pure XSLT any variable is fixed and its value cannot be changed. There
are, however, different approaches how to accomplish this. Most common is
defining template parameters and passing the proper values via them, see
below.

<xsl:template match="your-element" name="your-element">
   <!-- default value -->
   <xsl:param name="within-paragraph" select="0"/>
   <!-- your code -->
</xsl:template>

<xsl:apply-templates select="your-element">
   <!-- overriding a default value -->
   <xsl:with-param name="within-paragraph" select="1">
</xsl:apply-templates>


Btw, istead of 
<xsl:text disable-output-escaping="yes"><![CDATA[</p><p>]]></xsl:text>

you can write 
<p/>

Yes, functional programming requires different approaches, but I undestand
it can be tough. As for me in early stages :-)
