Accessibility reading order

Hi,

We are creating accessibility PDF through Acrobat Professional Xi and DC from PDF input. We have a below special requirements about reading order from our client for the following behaviour.

1. For cross-references to notes: Our customer wants to reads the Footnote citation, afterwards it should reads the corresponding Footnote text.   

2. For internal cross-references: Same as in above. Our customer wants to reads the internal cross reference such as year, then it should read the corresponding Author in the Reference section.

Also, internal cross references like, See Chapter2, See table 1.1, See figure 1.2 citations, We need to provide the Alt text like (Please see "Table 2.1" for your more reference)

3. For external cross-references and web links: The Alt text of the cross-reference should be read and then continue with the text of the paragraph.

Please let me know how could be automate this requirement in PDF using Adobe Acrobat Pro or is there any SDK available for this. Whether it is feasible to do in the SDK, please suggest.

Thanks,

Santhosh
