You're presenting false dilemma between properly generated well-formed XML  
and "tag soup". It is possible to properly generate HTML as well, and have  
it unambiguously parsed by all user agents. In fact, it isn't much  
different from proper way of generating XML. In many tools usually used  
for generating XML it's just a matter of changing output format from XML  
to HTML.

In case of controlling of an army, draconian handling of XML isn't enough,  
and relying on it would give false sense of security. Such important  
communication channel must use encryption and cryptographic verification  
of message integrity, which gives draconian error handling for any  
payload, with true security.

I'm not advocating replacing of all XML with HTML, but only pointing out  
that calling HTML "toy language suitable for toy use cases only" is a  
great exaggeration and ignores the fact that HTML has proven to be  
suitable for 99% of the web so far. I wouldn't even be surprised if HTML  
mail was involved in controlling of some armies today.
