The schematron sources have several variants of this, targetting
different use cases. using name() is fine for human-oriented paths in
error reprorting etc, but if you need to execute the paths the problem
is thatit uses namespace prefixes from the  source file, so you need to
bind the same prefixes in the context that the xpath is executed.

   <xsl:template match="*" mode="xpath-step">
     <xsl:text>/*</xsl:text>
     <xsl:if test="count(../*) > 1">
       <xsl:text>[</xsl:text>
       <xsl:value-of select="count(preceding-sibling::*) + 1"/>
       <xsl:text>]</xsl:text>
     </xsl:if>
   </xsl:template>

makes xpaths that are a bit less informative to a human reader  /*[33]
instead of /xhtml:table[2]  but don't have a dependency on namespace
context.

(variants of this generate /*[local-name()='table'][2] or (for xpath 2)
/*:table[2] if you want a version which shows the variable name but
without namespace dependency)
