With the log file below I'm trying to register ahelp collection and
plug one into another (vs 2008).the remobjects.oxygene namespace
register fine but doesn't plug into it (though it registers fine,
error only says registration failed). However the keyword list for
remobjects.oxygene does show opening vs.net help, the TOC however does
not show. I tried registering the remobjects.oxygene one under another
namespace but that also fails. the original (before compilation) hxt
file for remobjects.oxygene looks like:

<?xml version="1.0"?><!DOCTYPE HelpTOC><HelpTOC DTDVersion = "1.0"
LangId = "1033" ParentNodeIcon = "Book" PluginStyle =
"Flat"><HelpTOCNode Title = "Delphi Prism" Icon="0" >
<HelpTOCNode Title = "Main Method - Delphi Prism"
Url="Main_Method.html" />
<HelpTOCNode Title = "Language - Delphi Prism" Url="Language.html" />
</HelpTOCNode>
</HelpTOC>

the hxc looks like:

<?xml version="1.0"?>

Currently I'm only deploying the compiled .hxs file. What can I check
to figure out where this error comes from and what i can do to fix it ?
