What is this SVG XLink meant to do

Question

I am working with an image that has XLinks such as follows: -

<defs>
  <path id="SVGID_1_" d="M0 0h250v182.6H0z"/>
</defs>
<clipPath id="SVGID_2_">
  <use xlink:href="#SVGID_1_" style="overflow:visible"/>
</clipPath>
<g style="clip-path:url(#SVGID_2_)">

There are 1/2 doz of these that all seem to (my first guess) suggest go to previous section?

I can understand external links but can someone please shed some light on what the author may have been intending here? the common denominator seems to be: - d="M0 0h250v182.6H0z"

Can I just get rid of them?

EDIT

Thanks for the answer @qrsngky

The author repeats this 3 different times in the one document so clipPath must be difficult or d="M0 0h250v182.6H0z" may be the copyright who knows.

Anyway I replace the Xlink:hrefs with hrefs so I can drop the namespace reference.

Cheers
