        Reading the code to the LXBrowser program suggests the implementation 
is relatively straightforward.  I'm already in a C++ document/view 
architecture, so I guess I'm at an advantage here.  I have been using the 
Stingray XML serialization tools here, but being based on the MS XML DOM, the 
performance on large complex datasets is unusable, so this is not a solution.  
The underlying XERCES XML SDK used in the LandXML SDK appears to offer good 
performance and is well documented.  That said, I'm very surprised that a 
project the size of the LandXML SDK doesn't have any of its own developer 
friendly documentation.  It makes you wonder who the indented audience for this 
SDK is.  I've spoken to two other developers at land survey conferences who 
have implemented LandXML, and neither have used this SDK.

To get the SDK to work with Access, I'd probably build a project based on the 
LXBrowser example, get rid of the view class, and use a CDAORecordSet derived 
class to copy to an from Access.  A total hack, but pretty easy to implement.  
If I get my head around the SDK, I'll try to put an example together.  What 
language and dev environment are you using?

I tried to use the SDK, but was lost, without a clue where to begin.
I wanted to use Access, and have already dveloped a module that reads
XML and builds linked tables.  Access is supposed to be able to then
save an XML file, but I've had problems making it work. 
If you have some luck with the SDK, I would like to know more about how to make 
it work.

        I'm in the process of adding LandXML support to our land survey 
package, see
        http://www.atlascomputers.ie/index.php?page=SCC-Overview, and plan to 
        the current SDK (LandXMLSDK1.1-04062007.zip) to do this.
        Is there any documentation or tutorial information associated with this 
        or is the intended usage  to learn the SDK through investigating the 
        samples?  Alternatively, can anyone recommend an approach to 
        LandXML?  We are currently working in Visual C++ 7.1, so the SDK seems 
        a good approach.
        Thanks and best regards,
