• Colors
  Both spot colors and process colors are supported.
• Paragraph styles and character styles
  All paragraph and character attributes are supported.
• Anchored frames
  All types of anchoring positions are supported.
• Tables
  All table attributes are supported. Table title, missing in InDesign, is interpreted as additional table header/footer row.
• Graphics and Layout
  All graphic objects are supported. Graphic frames are interpreted as grouped objects.
• Sideheads
  Sideheads are interpreted using margin in text frames and new anchored text frames.
• Auto numbering (in CS3)
  FrameMaker's auto numbering feature is transformed into Lists in CS3. Named lists are supported.
• Variables (in CS3)
  All system and custom variables are interpreted into CS3's variables or custom variables.
• Cross-References
  The entire cross-references functionality can be preserved using DTP Tools Cross-References Plug-In for InDesign
• Extensive font substitution options
  It's possible to substitute font families and font faces during the conversion, especially when converting documents from Mac OS 9.
• Extensive character encoding support
  Supported character encodings: Western, East Europe, Hebrew, Arabic, Greek, Russian, Turkish, Baltic

With CS4 Adobe added support for conditional text to InDesign. From CS4 up MIF Filter does convert conditional text into InDesign format.

• Equations
  Mathematical equations are not supported; nevertheless, we are considering creation of supporting plug-in similar to the one for Cross-References.
• Conditional text in CS2 and CS3
  Visible conditional text is imported, hidden conditional text is lost; nevertheless, we are considering creation of supporting plug-in similar to the one for Cross-References.
• Floating objects
  An attribute "floating" for anchored objects and tables is not supported.
• Anchored objects
  Anchoring position "At Top of Column" is not correctly interpreted (such object can't have text wrap).
• Sideheads
  Text within sideheads can't flow to another page.
• Auto numbering
  The definition of autonumber format can't contain more than one tab and non-incrementing blocks (<n>)

MIF Filter converts between cross-platform files too. You can open Windows documents on Mac and vice versa. All non-European language text is converted correctly between any combination of platforms.

These documents are standard FrameMaker sample files, converted by MIF Filter to InDesign CS2.
