[TxMt] PHP "Here document" syntax + coloring

[minimal.design]

I was just writing this PHP form thing and I like to use the "here  
document" syntax for it.  While it technically makes sense that the  
whole block within the <<<TAG [ ... ] TAG; is colored as a string, it  
makes it hard to read a large block of let's say HTML (kind of a very  
usual use for it)...  Is there anyway to keep the HTML within colored  
as regular HTML?

Hope my question makes sense :)

Thanks
