No, at least with MSXML:

1. The explicitly specified attributes come first.

2. Then come the attributes from the DTD -- in the same order they were
declared in the DTD -- not in alphabetical order.

3. I found what seems a bug in MSXML -- see below. I will make a
"cleaner" experiment in order to be sure about this.

I made a quick test using the XPath Visualiser and IE.

The source xml document (docWithDTD.xml):
---------------------------------------
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE gifts [
<!ENTITY nbsp "&#160;">
<!ELEMENT gifts (ModelNumber+)>
<!ELEMENT ModelNumber (#PCDATA)>
<!ATTLIST ModelNumber
               group (gold | red)  "red"
               dep (gold | red)  "red"
               prod (gold | red)  "red"
               location  CDATA    #IMPLIED 
               ref  CDATA    #IMPLIED 
               id  ID    #IMPLIED  >
]>

<gifts>
  <ModelNumber dep = 'red' group="red" prod="red">P6205 *
1103</ModelNumber>
  <ModelNumber dep="gold" group="red" prod="gold">P6205</ModelNumber>
  <ModelNumber dep="gold" group="red" prod="gold">1103</ModelNumber>
  <ModelNumber prod="gold">P6205</ModelNumber>
  <ModelNumber>1103</ModelNumber>
</gifts>

IE displays:
-----------
-<gifts>
<ModelNumber dep="red" group="red" prod="red">P6205 *
1103</ModelNumber>
<ModelNumber dep="gold" group="red" prod="gold">P6205</ModelNumber>
<ModelNumber dep="gold" group="red" prod="gold">1103</ModelNumber>
<ModelNumber prod="gold" group="red" dep="red">P6205</ModelNumber>
<ModelNumber group="red" dep="red" prod="red">1103</ModelNumber>
</gifts>


The XPath Visualiser displays:
-----------------------------
-<gifts>
<ModelNumber dep="red" group="red" prod="red">P6205 *
1103</ModelNumber>
<ModelNumber dep="gold" group="red" prod="gold">P6205</ModelNumber>
<ModelNumber dep="gold" group="red" prod="gold">1103</ModelNumber>
<ModelNumber prod="gold" group="red" dep="red"
prod="red">P6205</ModelNumber>
<ModelNumber group="red" dep="red" prod="red">1103</ModelNumber>
</gifts>


Also there might be a bug in MSXML3 -- notice how there are two "prod"
attributes for the 4-th "ModelNumber".

Cheers,
Dimitre.
