What is the valid text node value for my SCORM 1.2 prerequisites?

Question

I am trying to create a sequenced SCORM 1.2 package with multiple modules in the package. Specifying multiple item identifiers creates invalid XML though.

From ADL's "The SCORM Content Aggregation Model" (go to section 2-139), the text node value used is:

<adlcp:prerequisites type="aicc_script">R1&R2</adlcp:prerequisites>

So the XML chokes on the ampersand between R1/R2. What do I use instead of the ampersand character? I tried a comma which worked in Moodle but not Saba.

My manifest contents:

Try using & which is the preferred way of escaping ampersands (See also How do I escape ampersands in XML so they are rendered as entities in HTML?)

(I just tried it in a LMS and it worked)

I'm a step closer now, thanks periklis, the manifest didn't die in a ball of flames, but the SCORM 1.2 sequencing also didn't pick up in Saba as it did in Moodle. I'd say it's something else :/ – danjah Jun 20 '12 at 21:58
if you try using a single prerequisite, does it get through? Also have you tried importing the default multiple SCO from ADL, "Maritime Navigation", to see if Saba supports it? – periklis Jun 21 '12 at 07:59
Hmm, I couldn't actually find that directly named example - but i did find a bunch of other test packages, including SCORM 2004 sequencing, and a multi-SCO SCORM 1.2 package. Interestingly, Saba failed to comprehend the full-on 2004 sequencing. Also, the SCORM 1.2 "MultipleSCOEx.zip" didn't do anything sequencial, and SCORM Cloud service threw Javascript errors with that example. – danjah Jul 11 '12 at 03:01
