So, in the end, is mixing JSTL with JSF ok or not?

Question

At first, when I began learning JSF, I was taught not to mix JSTL into JSF because it's very hard to know how will be behave.
Then, I learned that in order to avoid the confusion completely, it was best not to use any JSTL or even better use Facelets.
Now, I keep running into (relatively recent) articles and books claiming both that JSTL now works with JSF and that it doesn't.
I gave it a shot by trying the famous c:forEach with h:outputText
<c:forEach var="item" items="#{someBean.items}">
    <h:outputText value="#{item.name}" /></td>
</c:forEach>According to my current knowledge, this is not supposed to work, and it doesn't, but since I've seen a Sun article saying that it should (if the latest components are installed, and they are), I can't be sure if I misconfigured something or...
I've also read the following sentence (regarding the above example):
>
This is supposedly fixed in JSTL 1.2, but there is no stand-alone implementation of JSTL 1.2.

So, could someone with an understanding of the issue clear this up for me? I'd be very grateful.
I'm not asking anyone to find out why my code didn't work, just if it was supposed to work at all.
Also, I found this on onjava.com
For instance, <c:if> and <c:choose> may contain JSF component custom actions, but only if the id attributes are set for the nested JSF component actions.It this true? Is it obsolete?
Thanks to anyone who takes the time to share any insight.

Thanks for the response BalusC, I'm now closer to understanding the issue. The only thing still bothering me is this code (taken from Sun's webtiersample.jsp)
<c:forEach items="#{BooksBean.books}" var="book" varStatus="stat">
     <tr>
          <td>
           <h:outputText id="title" value="#{book.title}"/>
       </td>
         <td>
           <h:outputText id="author" value="#{book.author}"/>
         </td>                          
     </tr>
</c:forEach>Won't this cause an id clash? I mean, doesn't this mean I'll have multiple "title" and "author" ids?
This seems to confirm the statement I quoted earlier (from onjava.com):
For instance, <c:if> and <c:choose> may contain JSF component custom actions, but only if the id attributes are set for the nested JSF component actions.Mind you, I don't really plan to use JSTL in JSF, but I really wish to understand this...
Thank you very much for taking the time.
