I get a NotSupportedException when I parse the following string with an XElement:
<ref>S. L. Vartanyan*, V. E. Garutt† & A. V. Sher‡parallel, "Holocene dwarf mammoths from Wrangel Island in the Siberian Arctic", Nature 362, 337 – 340 (25 March 1993) [http://www.nature.com/nature/journal/v362/n6418/abs/362337a0.html Nature.com]</ref>
Does anyone know why I get this error?
