gdt gets translations for strings that are going to go into the output 
documents.  The argument is usually plain text but can be Texinfo code.  
Hence, it has the same quoting conventions as Texinfo, where "<" stands 
for itself.  The tree returned is the same type as the parse tree for 
the whole Texinfo document.  It's not easy to add in a <span> here, as 
this tree is not specific to any output format.

The --no-number-sections option to texi2any should stop the section 
numbers being output.
