I have an Article
schema for my structured data. I've three part of title like "Up title", "Main Title" and "Lead":
<section itemscope itemtype="http://schema.org/Article">
<h2 itemprop="name">
This is up title
</h2>
<h1 itemprop="headline">
This is up title
</h1>
<h3 itemprop="about">
This is lead
</h3>
Which property should I use for each title?
And is there any limitation for using multiple of the same property like two or more headline
in my example?
