Re: RFE: Improved whitespace treatment

If I had ever learned how "mixed mode" affects white space handling in 
XML (I probably did learn it 5-6 years ago), then at least I had 
forgotten it ..

Thanks for the advice to modify the DTD. I guess will do that - if you 
don't do it. Because:

XMLmind has made a few willful violations of the HTML5 spec, such as 
permitting the border attribute for the table element. Amd I think it 
would be very meaningful , perhaps more meaningful than allowing the 
border attribute for table, to limit the content model of <body>, 
<section> and perhaps some other HTML block elements as well, to a model 
where text nodes are unpermitted. And why not do the same for the DITA 
<section> element.

Remember, as well, that the current behavior causes aiuthors to - 
unwillingly - commit errors in the form of text nodes as direct children 
of <body> and <section>.
