A notebook has the input-output cell pair:

   Limit[Sin[x]/x, x -> 0]
1

I do Save As Special XML (XHTML+MathML) to file limit.xml.  When viewed 
in a browser supporting native MathML (e.g., Mozilla 1.1), the input 
cell includes a spurious "\[Rule]" while otherwise displaying everything 
correctly, including the arror (which I show here as ->) with 
appropriately sized brackets:

Limit[Sin[x]/x, x -> "\[Rule\"0]

Specifically, the MathML source of the erroneoulsy generated input cell is:

  <b><p class="Input"><math xmlns='http://www.w3.org/1998/Math/MathML'>
  <mrow>
   <mi>Limit</mi>
   <mo>[</mo>

   <mrow>
    <mrow>
     <mrow>
      <mi>Sin</mi>
      <mo>[</mo>
      <mi>x</mi>
      <mo>]</mo>

     </mrow>
     <mo>/</mo>
     <mi>x</mi>
    </mrow>
    <mo>,</mo>
    <mtext> </mtext>
    <mrow>

     <mi>x</mi>
     <mtext> </mtext>
     <semantics>
      <mo>&#8594;</mo>
      <annotation encoding='Mathematica'>&quot;\[Rule]&quot;</annotation>
     </semantics>
     <mtext> </mtext>

     <mn>0</mn>
    </mrow>
   </mrow>
   <mo>]</mo>
  </mrow>
</math></p></b>
