Transforming HTML using XSLT is something that isn't really supported. 
It does mostly work, though as you notice you have to use lowercase 
names in patterns and expressions. The reason you have to use lower case 
is basically a bug due to internal implementation details.

Ideally patterns and expressions should be case insensitive when used in 
XSLT when transforming HTML nodes.

Feel free to file a bug on this, but in the mean time i'd recommend 
simply using lower case as a workaround.
