Restricting the length of a textarea

Is it possible to restrict the length of a textarea in a dcr, - maxlength only seems to work for text?

You're right, the maxlength only works for text. For textarea you'll have to write your own validation-regex. The following example limits input to a max of 120 characters:

<item name="Blurb">
<label>Blurb</label>
<description>This description will go under the headline link in the intranet main page.</description>
<textarea rows="3" cols="41" wrap="virtual" validation-regex="^.{1,120}$" />
</item>

Thanks,
That has been very useful, although it doesn't work very well within replicants!

There's a slight problem with your code. The dot character (.) matches anything but a newline, so the match will fail if the user has hit the return key or if wrap is set to physical. An alternative is to use a character class that will match any space character or any non-space character, a la:

[\s\S]{1,120}
