What are you expecting it to do?  In your DTD you say that the entity
LOGO is a JPEG external unparsed entity to be found at 'team.jpg'.  In
the XML you reference that entity, but an XML parser won't do anything
with that in particular, it's just a reference to that image.

If you want to, for example, create some HTML with an img element that
references that same image, then you need the
unparsed-entity-uri() function, which takes a (string) entity name and
gives you the URL for it, so in your case:

  unparsed-entity-uri('LOGO')

will give you the URL

  .../team.jpg

It gives you the absolute URL for the entity.

So you could do:

<xsl:template match="IMAGE">
   <img src="{unparsed-entity-uri(@SOURCE)}" />
</xsl:template>

to get the XSLT to generate an HTML img element for the relevant
image.

I hope that helps,

Jeni
