Alice,

It sounds like your user interface is one where the user types in an URL string. You could offer additional fields if they need to enter multiple name/value pairs (the only reason for an ampersand to appear in an URL). Then your xsl could construct the final URL, adding the '?' if any name/value pairs exist, and then outputting them with your own '&' and '=' characters placed between them.

Sample XML (constructed from text fields):
<userURL>
  <baseURL>http://www.someplace.com/dir/page.htm</baseURL>
  <pair>
    <name>arg1</name>
    <value>value1</value>
  </pair>
  <pair>
    <name>arg2</name>
    <value>value2</value>
  </pair>
  <pair>
    <name>arg3</name>
    <value>value3</value>
  </pair>
</userURL>

Relevant XSL:
<xsl:template match="userURL">
  <xsl:value-of select="baseURL"/>
  <xsl:apply-templates select="pair"/>
</xsl:template>
<xsl:template match="pair">
  <xsl:if test="position() = 1">
    <xsl:text>?</xsl:text>
  </xsl:if>
  <xsl:value-of select="name" />
  <xsl:text>=</xsl:text>
  <xsl:value-of select="value" />
  <xsl:if test="position() != last()">
    <xsl:text>&amp;</xsl:text>
  </xsl:if>
</xsl:template>

so the user has to input & or &3038; if their url consisys of an '&'.
