Introduction to tags
Tags have a name and can have some attributes, which help to return the good data.
One tag can be standalone or can be a "Iteration" tag through an array of elements.
For example, if you want to display all the articles of a page, you will need to loop through articles. The <ion:articles> will do this.
Example of standalone tag
<!-- Displays the title of the page or of the parent element depending on the context of usage --> <ion:title tag="h2">
Example of a iteration tag
<ion:languages tag="ul" id="lang" class="languages">
<!-- Displays the language name and links to the current content for each language -->
<li><ion:url /><ion:name /></li>
</ion:languages>
