http://www.dpawson.co.uk/xsl/rev2/functions2.html#d16818e694 has an 
example of hex to decimal conversion. I applied that to binary to 
decimal conversion as follows:

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:xsd="http://www.w3.org/2001/XMLSchema"
   xmlns:mf="http://example.com/2008/mf"
   exclude-result-prefixes="xsd mf"
   version="2.0">

   <xsl:function name="mf:bin2dec" as="xsd:integer">
     <xsl:param name="input" as="xsd:string"/>
     <xsl:sequence
       select="if (string-length($input) eq 1)
               then xsd:integer($input)
               else 2 * mf:bin2dec(substring($input, 1, 
string-length($input) - 1)) + xsd:integer(substring($input, 
string-length($input)))"/>
   </xsl:function>

   <xsl:template match="/">
     <xsl:value-of select="mf:bin2dec('10101010111')"/>
   </xsl:template>

</xsl:stylesheet>

but I have not tested in detail.
