In an SGML document (which a DSSSL stylesheet is), a reference
(&daisy;) to an external entity causes the entity to be parsed at that
point.  Compare &chapter1;.  So Jade has encountered:

entity-system-id: @#%^FHWDRGB CVNNFGYK^J^L
îK!J Të Q Jq
jelvbjxlkbj34;kl6 j1Tjgqe /lkj /26j /l j6 j6;1lkj6 ;l ;l6 k j53 j.nv
etc.

If you're only using the graphic in your stylesheet by filename, then
you could just change the entity definition:

<!ENTITY daisy "daisy.bmp">

so that the entity reference is expanded to the string "daisy.bmp",
which is an acceptable value for entity-system-id:.

There are DSSSL functions to find the system identifier of an entity,
but since you're not operating on the stylesheet itself, I'm not sure
they're applicable.
