seo - Schema.org setup for related products? -

i setup schema.org markup related products.

i have tried code have doubt in mind:

itemprop="isrelatedto" itemscope itemtype="http://schema.org/product" 

my product page https://www.amigotrekking.com/everest-base-camp-trek.html

• if it’s "functionally similar" product, use issimilarto property.

• if it’s "consumable" product, use isconsumablefor property.

• if it’s "accessory or spare part" product, use isaccessoryorsparepartfor property.

• if it’s "somehow related" product, use isrelatedto property.

so related product, microdata example be:

<article itemscope itemtype="http://schema.org/product">   <aside>     <article itemprop="isrelatedto" itemscope itemtype="http://schema.org/product"></article>   </aside> </article>
