Omni Systems, Inc. Mif2Go User's Guide, Version 55
> 15 Converting to DITA XML > 15.7 Specifying options for images in DITA XML > 15.7.4 Providing alternate text for images
To provide alternate text for an image in DITA,
you need an <alt>
tag. Instead of using
a GraphAlt marker, which causes
the content to become an attribute, you have to insert the text via the
FrameMaker Object Attributes dialog for
the anchored frame; see §31.4.2 Overriding graphics settings with FrameMaker object attributes.
Mif2Go produces <alt>
tags if and only if you use the FrameMaker Object
Attributes dialog. Place the text in the Alternate:
box under Text Attributes. Do
not place the text in the Defined Attributes:
box under New or Changed Attribute;
if you do, the content will become the attribute, which is deprecated
for DITA.
