Aspose has the ability to choose from PDF/A1a, PDF/A1b, PDF15, PDF/UA when converting a PPTX to PDF.
Among them, PDF/A1a was the equivalent compliance option when using Office ‘save as’ feature:

However, in some recent Office updates, Microsoft removed the PDF/A1 option and added the new PDF/A3 option.

You can see the text (19005-1 compliant in the option) disappeared in the latest Office 2019/365 versions.
There is also some conversation from the internet that is talking about this https://answers.microsoft.com/en-us/msoffice/forum/all/pdfa-1a-in-office-2016-for-office-365/a5ccad3e-fc33-4d7f-8c62-7c298a17a936

So my question here is, since Office now has the ability to produce PDF/A3 PDF, could Aspose versions also provide the same option? This would be very helpful to achieve the same good PDF quality as the PDF15 option but also keep the compatibility/accessibility of PDF/A.
