[Simple-support] Configure Persister to disable short closing tags?

[Vladimir V. <vla...@gm...>]

Hi,

I wonder is there a way to force persister to encode XML tags in long form
such as:

<img></img>

Currently I get:
<img/>

I need this to get XML output in correct format so I can calculate digest
for Canonicalization ext-c14n

Thanks
Vlad
