link tags inside body

Hi,

I’m getting links to the following two files inside my body tags which are throwing up errors in https://validator.w3.org :

/wp-content/plugins/slideshow-jquery-image-gallery/style/SlideshowPlugin/functional.css?ver=2.2.21

/wp-admin/admin-ajax.php?action=slideshow_jquery_image_gallery_load_stylesheet&style=style-light&ver=2.2.21

According to w3C there should be an itemprop attribute if a link is inside the body tag.

Thanks for any help.
