Escape PHP tags '<? ?>' on HTML Comments <!-- //-->

Hello, i am not sure if this is the supposed behaviour, but suppose i have the following code inside a template.

<!--
<?xml version="1.0" encoding="utf-8"?>
//-->

It will render as is, so having a problem regarding the generated PHP code because the <? ?>

Parse error: syntax error, unexpected T_STRING in ...

but since tal expessions are *not* evaluated inside comments i can't process it with a tal expression.

Shouldn't be the right behaviour to escape such characters when they are inside an html comment ?

I was thinking on implementing something like this on phptal for such case:

echo <<<uuid
<!--
<? blah blah ?>
//-->
uuid;

Waiting for comments ...

Slds.

PHPTAL allows PHP blocks in comments too (perhaps it shouldn't...) and you  
have short_open_tag enabled in php.ini, which makes all <? ?> blocks, even  
<?xml ?> interpreted as PHP code.

If you're not using <? blocks for PHP code (and always use <?php ) then  
you can disable short_open_tag setting.

Otherwise you need to change <?xml to something else or output it using  
<?php echo '<?xml'; ?>

ok, i will follow your recommendation and not use php short tags 
anymore, is it the recommended way from php developers too.
