Check out '5.4 of XPath 1.0.  A namespace nodes name is its prefix, and
its value is the URI.

<xsl:template match="document">
  <!-- This will be the providerns1 namespace node. -->
  <xsl:variable name="ns1"
    select="namespace::*[. = 'http://somewhere.com/']"/>
  <xsl:apply-templates
    select="entry[contains(@type, name($ns1))]"/>
</xsl:template>

That template should process only the entry elements whose type contains
the prefix bound to http://somewhere.com/.  (The contains() expression
should actually be more complex than that to avoid inadvertent substring
matches.)

That also wont work if the entry elements themselves define any relevant
namespaces themselves.  So dont do that. (-:
