What I mean by that is that PangoLayout gives paragraph formatting (how the lines are laid out) and PangoAttrType attributes and the markup language give the character formatting (applied to characters/words in the paragraphs).

What I want to do is to set the indent for the first line of each paragraph (it’s a numbered list and I want to set the indent -ve so that the numbers are left of the text). There is no way to do that in the Pango attributes/markup - what I need is pango_layout_set_indent().
