Ah, of course! I'm still learning to think in this new templating language. Is it 
possible to stack modifiers? For example, would the following be a valid:
    <option value="" petal:content=":encode :ucfirst title">Class Title</option>

Hmm, very interesting. I'll definitely keep this in mind.

Wow, that's interesting syntax in the condition element. I didn't realize that you can 
include parameters that will be passed to the object being evaluated.

While on the subject of conditions, is it possible to have Petal remove the tag the 
conditional is in if the condition fails? For example, I have a tag that looks like the 
following:
    <p class="error" petal:if"error_message" petal:content="error_message">Error 
Message</p>

If there is no error, the output will contain:
  <p class="error" petal:if"error_message" petal:content="error_message"></p>

I'd prefer to remove the p tag altogether. Perhaps I should place it into a span as 
follows:
    <span petal:if="error_message"><p class="error" 
petal:content="error_message">Error Message</p></span>

I like the simplicity of keeping it all together in the p tag but don't really want it 
printing the tag group if the condition fails.

Yes, that does sound like it would be the more straight-forward path.

Thanks,
