Folks,
Boy, this solves a bunch of problems for me, both with THREDDS catalogs and XML
FGDC files.
Thanks.

How to Handle CDATA Sections in XML Files
Using the Java[tm] Platform APIs for XML Parsing (JAXP)

We want to hear from you! Please send us your FEEDBACK.
The following article may contain actual software programs in source code form.

the terms and conditions of this license.
XML files often contain character data that an enclosing application requires to
extract as presented - for example, input data for a subroutine or XML markup to
be displayed in a browser. Any parser parsing the XML file should not interpret
this character data and present it to the application unchanged. Any character
data marked as a CDATA section in an XML file will not be interpreted by the
parser. An example of a CDATA section is as follows:
<![CDATA[Hello this is the content of a CDATA section]]>
All CDATA sections have three components: a CDATA start marker, ' <![CDATA', a
character content body. For example, "Hello this is the content of a CDATA
section", and a CDATA end marker, ']]>'. A CDATA section is often used for
character data that includes special XML characters, such as '&' and '<' that
need to be preserved for the calling application.

Hi Benno,
1) you can always use it. it is part of the basic XML syntax definition.
2) mail client behavior - i am constantly hitting reply thinking the
reply will go to the mailing list, but it goes to the sender instead..

Benno,
Have you considered using the CDATA marker?

Until you mentioned it, I had never heard of it.
1) can I always use it, or does it have to be declared in the DTD?
2) why didn't you post the suggestion to THREDDS -- I suspect I am not the
only one unaware.

I mention this only because it is an issue that should be addressed:
personally it seems more of a pain than anything else.
Text that I use to construct the contents of the documentation tag
<documentation>
This is the text I mean
</documentation>
occasionally has embedded html in it, mostly the <b></b> and <i></i>
needed to do paper references. These tags are technically illegal in
our xml document, so I am supposed to change the < and > to an entity
and then it will parse. That, however, changes the meaning of the
string, i.e. HTML no longer thinks they are tags, either. I could take
the tags out, but then I lose meaning, albeit not a lot.
So could we allow some formatting in the documentation? Alternatively,
can we allow meaningless tags as far as XML is concerned?
