It could be a good idea to use 2 distinct
funcprototype tags in cases in which the function
changed from PHP 3 to PHP 4.
Looking at the DocBook spec, a funcprototype can only
have one funcdef, and a funcdef can contain #PCDATA.
Also, a funcsynopsis element can contain one or more
funcprototype elements.
So we could use:
<funcsynopsis>
<funcprototype>
<funcdef>
(PHP 3) int <function>unset</function>
</funcdef>
<paramdef>
...
</paramdef>
</funcprototype>
<funcprototype>
<funcdef>
(PHP 4) void <function>unset</function>
</funcdef>
<paramdef>
...
</paramdef>
</funcprototype>
</funcsynopsis>
