What am I doing wrong? ("Debug" XML code help please.)

Hi,

xmllint --valid gives error output on some code (included below

file "Shotgun_Robot.dtd" (don't ask)

<!ELEMENT Image (#PCDATA) > <!-- #PCDATA == image path -->

<!-- x/y values default to 0, w/h values default to image w/h-->
<!ATTLIST Image
srcrect_x CDATA #IMPLIED
srcrect_y CDATA #IMPLIED
srcrect_w CDATA #IMPLIED
srcrect_h CDATA #IMPLIED
<!-- If element content is empty, the Drawable name points to an
already created Drawable. If it is not empty, it defines a
Drawable of the name and type given. -->
<!ELEMENT Drawable (EMPTY|Image|Mup)
<!ATTLIST Drawable
name CDATA #REQUIRED
<!ELEMENT Mup (Drawable)* >


file "image_test.xml"

<?xml version="1.0"?>

<!DOCTYPE root SYSTEM "Shotgun_Robot.dtd" [

</Drawable>
<Drawable name="t43a" />
<Drawable name="mup1" />
</Mup>
</Drawable>

</root>


error output:

This says that Drawable takes one of three elements as content:
EMPTY, Image, or Mup. What you want is

<!ELEMENT Drawable (Image|Mup)?
This says that the content is zero or one of either Image or Mup.
