Do something like this in a <remarks /> block:

<remarks> You should see &lt;something /&gt; here. </remarks>

When this renders, you won't see the word "something" inside the entity markings because they've been decoded and the browser is actually receiving them as literal < and > marks. They should be encoded before being displayed.

Note that this doesn't seem to happen in blocks. For example, the following renders properly:

GetObject<T>

This, however, doesn't work in code:

'apostrophe'

That code renders as:

'apostrophe'

Validated that this happens in both the NDoc and Sandcastle preview styles.

The fix for this has been committed to the trunk and should be available in the next release. As a side effect of fixing this, issue #16 (Special Unicode characters like German umlaut won't render right) has also been fixed.
