[wsrp][markup] Custom markup

Title: Message

I 
don't think it has been explicitly stated, but my impression from the markup 
discussion to date is that the spec will permit the portlet to insert custom 
markup in the output stream.  This is to say, transparent tagged data 
that is intended for the Consumer to do something with, but which is not 
recognized as belonging to a supported markup language.

 

I 
think this is an important capability to stress.  Many web applications 
exploit weak browser validation to embed useful non-HTML markup in the output 
stream, and we can anticipate that portlet producers will continue this 
practice.  Of course, we have an opportunity to make this more 
robust.

 

It may 
be useful for portlets to publish a schema for such data (part of the 
service metadata?), so that Consumers will have an in-band way to 
decipher it.

 

Thoughts?
