Tags in HTML attributes?

Question

I have a plugin that enable users to add on a caption to a image if they want to, using the title attribute. I would like to find out, if I allow them to do this :

<img title="I am a <myplugin-a>caption</myplugin-a>" src="imagelink" />

and then in my js, I would do a replace for "myplugin-".

Would this lead to any problems in terms of validation?

这不会导致有效性问题（标题属性中的数据小于等于字符且允许大于字符），但是这意味着如果不应用JS，您的HTML将是毫无意义的（用户可能禁用了JS，一个JS文件）可能无法加载，搜索引擎索引器通常不会执行任何JS等）。
