Is it possible to make an attribute required, optional, or forbidden
depending on the value of another attribute? How about changing
element content based on an attribute?

Sure - just not with W3C XML Schema <g>. You can supplement XML Schema with
Schematron or just write a custom XSL transform that produces output
describing any rules if finds to be broken.

What about other schema languages? Does RELAX NG, for example, have
this ability?

I'm not a RELAX NG user because it isn't supported for what I need, but I am
led to understand that it cannot do things like that, and that Scehamtron is
pretty much the only schema language that can.
You can embed Schematron in either XML Schema or in RELAX NG, and most decent
XML editors can use the embedded Schematron if you tell them to (I use
<oXygen/> for this).
I'm starting to see, though, that even though it's a separate file and a bit
harder to keep clean and legible, using a custom xsl file might be the better
way to go. For one thing, you can use XSLT 2.0 without worrying about whether
your editor supports XSLT 2.0 functionality in Schematron, and for another
thing, you don't have to figure out how you're going to use Schematron to
validate documents in an application using, say, MSXML. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I've read a lot of posts on "why relax ng is so very good" and on "why
w3c xml schema should be the only schema language". I'm, however,
still not clear on why I should prefer one over the other.
I've made a small list of some good and bad points of both. These
points don't really go into the grammar aspects of these languages,
but are more about secondary aspects. The grammar aspects are
different, but both are suitable for validating...

Hi,
I've got a simple console app that just reads an XML file into a DataSet
then prints out a description of each table in the DataSet, including
column names and row values for each column. I'm getting some strange
results depending the input XML file I use. I was wondering if somebody
could help me understand what is going on or point me to a good reference.

I have data coming from SQL Server and need to write out some XML. I
have a schema(xsd) for this XML file. Right now I am bringing in the
DataSet and writing out the elements and attributes myself using
xmltextwriter to match schema without really using the xsd at the time
of writing.
The file I create validates but I was wondering is there a better way?
I see things like inferschema method off of dataset, can this be used?

I needed to serialize and deserialze two objects which inherited from

I called it XmlHashtable. It has, among other convenience methods, a method

Hello!
I know this might not be the appropriate forum for xml question.
But xml is so important for .NET I hope my basic question can be answered in
this forum.
I just wonder does every xml document have a XSD schema or XDR schema ?
Is it possible to say that the purpose for schema is to have a definition
for syntax.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
