Richard Kirby updated TAP5-1312:
--------------------------------

    Attachment: TAP-1312-diffs

A wee implementation of my suggestion.

I have tried to minimise the impact across the public API.

A custom component needs to cast MarkupWriter to MarkupWriter2 to access the new writeStream method. The fallback being to just create a String and use writeRaw.

> I would like a new org.apache.tapestry5.dom node that takes an interface which provides a callback method that is passed the PrintWriter being used when toMarkup is called.
> One usecase for this is where you want to insert a large chunk of raw text into a page that is coming from a streamable source (such as the output of a XSLT processor) and so is really not needed to be rendered into a String beforehand (which is what the MarkupWriter.writeRaw would require).
