What is "virtue of atomic element"

[terras]

What is the meaning of "virtue of atomic element" ?

The phrase comes from the sentence below.
"Structured data permits the interpretation of its content by virtue of atomic elements that are understandable by an

application and indivisible."
(This sentence is from the "NIST Special Publication 800-53. Revision 3 APPENDIX F AC-4 Control Enhancements8)" .
The document can be viewed by searching the file "sp800-53-rev3-final.pdf".)

The word "Structured data" can be explained as "data within the database", but I cannot find the relation with the words "virtue

of atomic element".Is it some kind of figurative expression ?
In addition, "application and indivisible" seems to be used as a similar or same level of words, but I cannot find any relation

to these words.

Hello,

I reckon that maybe a synonysm can help you in this situation. If you change this word by characteristic.

Bye,

The expression "by virtue of" simply means "because."

I don't understand the passage, but you can rewrite it as "Structured data permits the interpretation of its content because of atomic elements that are understandable by an application and indivisible."

How these atomic elements allow you to interpret the content, I just don't know.
