/// <para>The normal way of doing things is to

/// turns the xml element into a schema association so we would not
/// have to check for both. In this case, however, I do not want

/// makes a change using Tools->Options.</para>
/// <para>If we have a file extension that is currently missing a default
/// schema then if we ship the schema at a later date the association will
/// be updated by the code if the user has not changed the settings themselves.
/// </para>
/// <para>For example, the initial release of the xml editor add-in had
/// no default schema for .xsl files, by default it was associated with
/// no schema and this setting is saved if the user ever viewed the settings
/// in the tools->options dialog. Now, after the initial release the
/// .xsl schema was created and shipped with SharpDevelop, there is
/// no way to associate this schema to .xsl files by default since
/// the property exists in the SharpDevelopProperties.xml file.</para>
/// <para>An alternative way of doing this might be to have the
/// config info in the schema itself, which a special SharpDevelop
/// namespace. I believe this is what Visual Studio does. This
/// way is not as flexible since it requires the user to locate
