Finding that the Format Attributes documented here are not the same as the ones that are showing up when I use the Microsoft PowerPoint writer within a FeatureWriter transformer (see screenshot below and look for the pptx_title_text parameter):

@dmatranga thanks for pointing that out. We'll get the documentation updated. The attributes you are looking for;
pptx_slide_order
pptx_styler_id
pptx_sub_order
pptx_subtitle_text
pptx_title_text
pptx_type
Are created by the PowerPointStyler transformer
