According to http://www.jclark.com/xml/xmlns.htm
this XML could be mapped (only interesting parts are left) to
the following imaginary syntax:
    <{http://books}review {http://zork}style="font: sans-serif">...
    <{http://zork}p style="font:serif">...
Then the following rules can be used to match the attributes:
    <xsl:template match="@html:style">... -- for the first "style" attribute
    <xsl:template match="@style">... -- for the second "style" attribute
because the expanded name is used to locate the nodes
according to http://www.w3.org/TR/xpath#section-Location-Steps

As to Void and non-Void namespace for the attributes the XPath
Recommendation 1.0 tells the following:
    The namespace URI of the attribute's name will be null if the QName
    of the attribute does not have a prefix.
(see http://www.w3.org/TR/xpath#attribute-nodes).
