Text in a slide, notes page or table cell is DrawingML, in the namespace
http://schemas.openxmlformats.org/drawingml/2006/main, shortened to

Bullets and levels
A paragraph’s lvl attribute picks a level in the master’s text styles, which
usually set a bullet for each level of body text. a:buNone removes the
bullet, a:buChar sets a character, a:buAutoNum numbers the
paragraphs and a:buBlip uses a picture.
Hyperlinks
A run’s a:hlinkClick has an r:id pointing to a
hyperlink relationship, with the target there. Actions such as
“next slide” use the action attribute instead.
The explorer shows a link only when its target is a web or mail address, and shows other targets as plain text.
