do it the same way.  Building the document in XmlTextReader is fine by me, as 
long as the non-document API functions sufficiently to fool apps that use it.  

There are some advantages to using the node forms internally: the rest of the 
XmlNode code can be reused to implement bits of XmlTextReader, rather than 
having to duplicate that work.  Anyway, at this point the motto is "whatever
