attributes - How to identify a section in an Evernote's note to update it later -

i making app automatically creates notes evernote based on government api , need update these notes if government api change something.

but thing is, evernote uses superset of xhtml called enml , doesn't allows me use "id" or "data" attributes in tag.

my question how can identify 1 tag or section in note i've created change/update later.

we had same issue, wrapped inner html traceable span this:

<span style="x-your-business-name:section;">here put inner html content</span> 

at point it's xhtml traversing , updating. span doesn't influence in way display of evernote note.
