How do I put CSS correctly in an SVG rendered in the view via the use tag?

I'm using AngularJS to load an element, but it does not grab the CSS.

A View:

 <svg version="1.1" id="body_1" data-name="body-1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
       viewBox="0 0 196.5 445.5" style="enable-background:new 0 0 196.5 445.5;" xml:space="preserve">
    <use xlink:href="" class="content-body" ng-href="{{arquivo + '#content_body'}}" /></svg>

In the file variable control:

$scope.arquivo = '/img/body.svg';

The SVG file:

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet href="css/body.css" type="text/css"?>
<svg version="1.1" id="body_1" data-name="body-1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
     viewBox="0 0 196.5 445.5" style="enable-background:new 0 0 196.5 445.5;" xml:space="preserve">
    <g id="content_body">
        <style type="text/css">
            .clip-path-body-1{clip-path:url(#clip_body_1_4);}
            .body-1{clip-path:url(#clip_body_1);fill:#C4E0F6;}
        </style>

CSS that does not handle (css / body.css):

.content-body .clip-path-body-1{clip-path:url(#clip_body_1_4);}
.content-body .body-1{clip-path:url(#clip_body_1);fill:#C4E0F6;}

Where am I going wrong?
