XML for basic structured web pages

Hello,

I did a search on the web trying to find general XML
Schemas that people use for Web content, like press
releases, job descriptions, product descriptions,
whitepapers, newsletters, etc.  I was surprised that I
couldn't find any. Are people just not storing this
type of content in XML?

Should structured Web content like press releases and
job descriptions be stored in XML?  What is the most
important benefit of doing so?  Is it for repurposing
the content or easy, quick redesign, or improved
searching?  Finally is anyone really doing this or are
the benefits of storing this type of content in XML
not worth the pain of writing schemas and XSLTs?

Thanks,

Nat
