Do weex support richtext?

[wcxwave]

Hi everyone!    Happy New Year!    About richtext, I see the link:  
https://hanks10100.github.io/weex-vue-examples/#component/richtext.    which 
use element <span> etc, ex:       <richtext class="richtext">
        <span class="label">图片：</span>
        <image style="width:222px;height:81px" 
src="http://img.alicdn.com/tps/TB1wXN_PpXXXXbgapXXXXXXXXXX-222-81.png"; />
        <span style="font-size:35px">
          <span class="grey">这是一段很长的文字，虽然很长但是并没什么卵用，只是用来测试能不能换行。</span>
          <span>
            <span>如果这些字会</span>
            <span class="text-bold">变大变粗</span>
            <span class="text-thin">变小变细</span>
            <span style="color:#FF6600">还能变颜色</span>
            <span>，就说明富文本组件能用。</span>
          </span>
        </span>
      </richtext>  I think the richtext component is very useful. But I can't 
use it in the formal release version. Do weex support such a richtext component 
in both android and iOS? When? Thanks!
