The depth of any node in the current tree can be requested with: 
count(ancestor-or-self::*)

Bonus: your stylesheet can be written a bit easier as follows:

<xsl:template match="section">
       <li>
           <xsl:apply-templates select="label" />
       </li>
       <ul>
           <xsl:apply-templates select="section" />
       </ul>
 </xsl:template>

 <xsl:template match="label">
    <xsl:apply-templates select="@href[@href != '']" />
    <xsl:value-of select=".[not(@href) | normalize-space(@href) = '']" />
 </xsl:template>

  <xsl:template match="label/@href">
     <a href="{.}"><xsl:value-of select="label" /></a>
  </xsl:template>



As a general hint, whenever you are writing an xsl:choose or an xsl:if 
with a node test, consider rewriting it as a matching template/applying 
templates pair. This will undoubtedly make your code more adept to 
change, efficient and easier to understand in the long run. A test for a 
label being empty and then outputting its value is unnecessary. It may 
happen that an empty <a></a> occurs but that still renders the same, if 
you don't like that you can remove it by changing the matching template to:

  <xsl:template match="label[.!='']/@href">
     <a href="{.}"><xsl:value-of select="label" /></a>
  </xsl:template>
