These days I am working on a personal project which I call “my precious”. This projects involves transforming XML documents into HTML using XSLT. Things were going smooth till I decided to output DOCTYPE from XSLT. This is what I did.

XSLT parser does not like the code above and gives me this error.

After scratching my head for a while and navigating through intellisense few times I found the right solution. The way to output DOCTYPE in XSLT is by placing in inside a CDATA. The following code works like a charm.

This I thought was worth sharing.
