Using XSLT, how would you extract a specific attribute from an element in an XML document?

Successful candidates should recognize this as one of the most basic applications of

at least be able to identify the components necessary for this operation: xsl:template to
match the appropriate XML element, xsl:value-of to select the attribute value, and the
optional xsl:apply-templates to continue processing the document.
