Is "markup" a noun or a verb? Do you "markup data" or "wrap data in tags"?

Hi Folks,

Consider this data:

    Nikon D40

Here I did "something" to the data:

    <camera>Nikon D40</camera>


Which is preferred way of expressing what I did to the data:

1. I marked up the data.

2. I wrapped the data in a tag.

3. I wrapped the data in tags.

4. I wrapped the data in a start-tag/end-tag pair.

5. I wrapped the data in markup.

6. I embedded the data in markup.

7. I enclosed the data in markup.

Or some other way?


I suspect that several of the above expressions are acceptable; which
ones?  

Are some of the above expressions just plain wrong, i.e. incorrect
English grammar?
