I am capturing XML over HTTP (filter: http && xml) and some of our XML data is
displayed in red.

Expanding the XML I see the message 

Unrecognized text
  [Expert Info (Warn/Protocol): Unrecognized text]
    [Unrecognized text]
    [Severity level: Warn]
    [Group: Protocol]

I have checked the XML with online validators
(http://www.xmlvalidation.com/?L=2) and as far as I can tell, the XML is
correct. Also, from the expand/collapse boxes, the XML is expandable in places
where it shouldn't be.

IMHO this is related to XML-like text data which is placed inside a <![CDATA[
item.

The following XML should reproduce the problem, it is a minimized and
anonymized version of the XML we're sending:

<?xml version="1.0" encoding="iso-8859-1"?>
<data>
    <![CDATA[
    <A0>
        <URL="" href="http://example.com/">http://example.com/ >    
    </A0>
    <**>
        <URL="" href="http://example.com/">http://example.com/ >    
    </**>
    ]]>
</data>
