HTML tags allowed in Blogger comments

I just discovered today that Blogger's comment system does allow some HTML tags within comments. The following HTML tags are OK to use...

<a> tags.

So you can use a tag like the following;

<a href="http://www.whatever.com">Check this out</a>

But Blogger does not allow any attributes to be used such as the target attribute as in...

<a href="http://www.whatever.com" target="_blank">Check this out</a>

Blogger allows the strong and bold tags for making text bold

Yes, you can use these tags to make text italicised.
