URL to address a page in a PDF which is in a mail?

Question

I search a way to address a single page in a PDF which is in an email.

Is there an official URL/URI spec which handles this case?

AFAIK there are these steps to get to the page:

1. address the mail.
2. address the pdf attachment in the mail (there could be several attachments in the mail)
3. address page number N in the pdf.

Answer 1

It is not possible to add a link to a specific attachment in an email, however it is possible to link to a specific page in a PDF externally.

To target an HTML link to a specific page in a PDF file, add #page=[page number] to the end of the link's URL.

If you host the PDFs somewhere instead of sending them as attachments you can get something close to what you want.
