In your stylesheet you will have to define prefixes for the namespace "urn:metoc:jmcbl:jmibl" and urn:metoc:jmcbl:jmcbl:jmibl and use them to explicitly qualify the references to JMO_obsList and other elements. Furthermore, the references to windSpeed and other XML attributes need to be referenced with the attribute: axis

An example of a complete value-of declaration:

<span style="color:blue">
   <xsl:value-of xmlns:ns1="urn:metoc:jmcbl:jmibl" 
   xmlns:ns2="urn:metoc:jmcbl:jmcbl:jmibl"
   select="ns1:JMO_obsList/ns2:JMO_obs/ns1:JMO_surfaceObs/@ns2:stationPressure"/>
</span>
