Invalid name character in 'atom:link'. The ':' character cannot be included in a name

Invalid name character in 'atom:link'. The ':' character cannot be included in a name

What? I have the atom namespace declared correctly and I'm wondering why the 
XmlWriter has a problem with this element? Does anybody have suggestions how 
to write XML that supports the Atom Publishing Protocol?

Are some writers in the framework "better" than others in this context? 
Which please...

Can you show us your exact code that gives the error?

// some statements wrapped for NNTP clarity...

XmlWriterSettings settings =
new XmlWriterSettings();
settings.CheckCharacters = true;
settings.CloseOutput = true;

using (XmlWriter writer =
XmlWriter.Create(writerFileMapPath, settings))
{

writer.WriteStartDocument();
writer.WriteStartElement("rss");
writer.WriteAttributeString("version", "2.0");

// Atom namespace
writer.WriteAttributeString("xmlns",
       "atom", null,
       "http://www.w3.org/2005/Atom");
...
// W3C recommended usage for link element
#region Task: <link> element...
if (link.Length != 0)
    writer.WriteStartElement("atom:link");
    writer.WriteAttributeString("href", link);
    writer.WriteAttributeString("rel", "self");
    writer.WriteAttributeString("type",
           "application/rss+xml");
    writer.WriteEndElement();
#endregion
...
writer.WriteEndElement();
writer.WriteEndDocument();
writer.Close();
}

Re: Invalid name character in 'atom:link'. The ':' character cannot be included in a name

BTW, I'm working on conformance with the current W3C recommendations...

// W3C validator recommendation
http://validator.w3.org/feed/docs/warning/MissingAtomSelfLink.html

// W3C example
<atom:link href="http://somewhere.com/rss.xml" rel="self" 
type="application/rss+xml" />

What remains ambiguous is the former link element has been used to refer to 
the location of the channel itself and not neccessarily a file, i.e. 
<link>http://mydomain.com/</link> but this documentation is FUBAR AFIC and 
apparently gives an example for a linked item of a feed which is always a 
file and not perhaps the channel's link element?

Still, how to write this with the XmlWriter has alluded me all day...

Re: Invalid name character in 'atom:link'. The ':' character cannot be included in a name

The documentation sucks, there is an overload. Intellisense gave me the clue 
but it wouldn't give me the list of overload constructors(is there a 
keystroke or some way to get the list of overloads from Intellisense?)

// This is how conformance to W3C atom:link element is written using the 
XmlWriter...

#region Task: <atom:link> element...
if (link.Length != 0)
    writer.WriteStartElement("atom", "link", null);
    writer.WriteAttributeString("href", link);
    writer.WriteAttributeString("rel", "self");
    writer.WriteAttributeString("type", "application/rss+xml");
    writer.WriteEndElement();
#endregion

// generates the following
<atom:link href="http://somewhere.com/" rel="self" 
type="application/rss+xml"/>

//still working on how to use XmlWriter using writer.WriteFullEndElement()
<atom:value>inner text</atom:value>

Use
      writer.WriteStartElement("atom", "link", atom);
