[TYPO3-mvc] nesting shorthand syntax? Or how to get XML-friendly URLs?

[Franz Koch]

Hi,

is there a way to nest viewHelpers in shorthand syntax? I tried it, but 
Fluid didn't parse it anymore.
My problem is, that I need to create XML files for Flash containing URIs 
in the following way:

<link uri="http://uri" target="whatever" ...>Some link content</link>

But the &-signs are not properly encoded to &amp; - so I tried to do it 
by using a htmlspecialchars viewHelper. But nesting didn't work.

Any idea besides creating my own :uri.action viewHelper?
