[Typo3] 'Skip navigation' anchor not working

[Robert Markula]

I use a 'skip navigation' link on top of each page, so that e.g. blind 
visitors may jump directly to the content.
The skip link looks like this:
<a href="#content">Jump to the content</a>

And in the content
<div id="content">
...content...
</div>

I even tried
<a id="content" name="content" />

It works on static pages, but in typo3 (with realURL enabled), the skip 
link jumps to the content section all right - but always on the start 
page. No matter on which subsite you are, clicking this link always 
brings up the content section of the start page. Hovering over the link 
shows up the url http://www.domain.tld/#content (instead of e.g. 
http://www.domain.tld/subsite/#content. And I don't know why. Is this 
possibly related with realURL?
