Data Elements timing in DTM

Are data elements processed based on the tags using them or are they processed at a specific time on the page? 

For example, a data element using custom JS is configured to pull a text value from an HTML <A> tag that isn’t available until the middle of the <body> tag.  If I have a tag that fires in the head and another that fires in at the closing body, will the header tag not include that data element but the footer tag would?

Data Elements are “use it or lose it”.   If you define a Data Element in the UI but never use it in any rule, it will never be populated. 

When you call a Data Element in a rule, DTM then looks for your definition of that Data Element, and THEN populates it.
