W3C-Issues

In the post options of UAM I set something like this in the post content field (to be shown before the more-tag):

<p class="note">You need a <a href="http://www.domain.com/login"/>login</a> for this post.</p>

But that doesnt work, because after I update the settings it escapes the quotation marks with backslashes:
<p class=\"note\">You need a <a href=\"http://www.domain.com/login\"/>login</a> for this post.</p>

So I need to enter it that way:
<p class=note>You need a <a href=http://www.domain.com/login/>login</a> for this post.</p>

That works, but produces a lot of W3C-errors:

an attribute value specification must be an attribute value literal unless SHORTTAG YES is specified
document type does not allow element “p” here; missing one of “object”, “applet”, “map”, “iframe”, “button”, “ins”, “del” start-tag
an attribute value specification must be an attribute value literal unless SHORTTAG YES is specified
NET-enabling start-tag not immediately followed by null end-tag
end tag for element “a” which is not open

I tried it with entities like <p class=&quot;note&quot;> ... but that doesn’t work neither.

I had this issue before, but it was never resolved:

So how can I set up a login-note to my visitors without W3C-errors?
