CMS not ex****ting links within an xmlplaceholder

A few months ago I posted a question regarding why sometimes resources were

not being ex****ted using the CmsDeployServer.CmsDeployEx****t.1 object.  I 
stated that the links (Pdf files) were created on the fly in a user
control, 
using c#.

Stefan explained that because these links were not stored within the cms 
database, cms was not aware of them, since the links were rendered at run 
time and consequently could not ex****t them.

If I now say that they are in fact stored as xml within an xml place
holder, 
does that change anything?

I did attempt to find my original post and reply to that one, but could
not 
find it.

Thanks
