email with ics (calendar) shows type/text

Even though the email has html content, the main type shows up as text (with sub-type calendar) when processing with $mime->Analyze. I am not sure, but is this right?
Usually if type is text, we would not expect Alternative to be there further down. Or am I missing something here?
Thanks for this great class.

It is hard to tell without seeing an example. Can you please show an example of a message with that problem complete with headers and body?

Thanks M,
here's the zip with source and output: http://plaenit.com/itms/ics.zip

Yes, the class is working as expected.

The message has 3 alternative parts of types: text/plain, text/html and text/calendar.

The rule is to take the last your application supports as main type and the others as alternatives.

Oh, I didn't realise such a rule takes precedence! Many thanks!

Yes, it may not seem evident, but that is the way it works.

Usually HTML messages have a text alternative part that always comes first in the message for old mail readers that only recognize text messages.

So in your case, the last part is the text/calendar part, which is probably to be interpreted by automated scripts. The first two parts should be for humans to read.
