Another problem is:

 

I have a custom tag <portal:xxx param1="value1" .../> and the format is modified

 

Exemple:
<portal:pagelink class="mentionlink" Label="Label" Name="Test"/>

Becomes:

<?xml:namespace prefix = portal /><portal:pagelink class=mentionlink Label="Label" Name="Test"></portal:pagelink>

 

- the    <?xml...    tag added is not a problem

- the end tag    />    replaced by    ></...>    is not a problem

- but the format    class="mentionlink"    without cotes IS a problem for me
