Ken - this is a developer support mailing list and as such, incorrect
statements
sometimes will get posted; we are not all experts at everything (my specialty
happens to lie with the Oracle RDBMS and even then I'm not an expert). I
apologize if what I indicated (wrongly) might mislead others. Thankfully,
persons such as yourself and Michael Blakeley of MarkLogic are around to
correct
such inaccuracies.
Bottom line, Marklogic has a bug that allows invalid XML to be successfully
saved but then chokes when replicating that invalid XML using their own,
internally developed replication code.
Regards,
Allen

If it did, it would not be conformant to the standards.

Yes, they should! CDATA is only syntactic sugar so as not to have to
escape markup on a per-character basis. CDATA is not information and
is not recognized in the XPath data model. CDATA is *not* something
that is preserved by conforming engines. There is no difference in
the data model between:
This is <![CDATA[a]]> test.
and
This is a test.

That error is bona fide because when using XML 1.0 you cannot use the
character $ ... if you want that character, then it is obvious
you have to use XML 1.1. You can see an example of me using XML 1.1
for that character (as ) in this XSLT stylesheet:
http://sportsmlt.svn.sourceforge.net/viewvc/sportsmlt/2.0/support/sportsmlt2-character.xsl?revision=13
In the future, I suggest you be careful not to make such broad and
incorrect claims that may be misleading readers of the archive into
believing things that are not true.
I hope this helps.
