Table management: Menu and toolbar Paragraphs: Easy to change types through dialog boxes	Spell checking Find and replace Change tracking List management: To convert bulleted list to numbered list, you have to remove tags and add new tags. Table management: Toolbar Paragraphs: A little more work to change paragraph types; you have to use the pop-up list and drill down to sub-lists.
Working with attributes and elements	Has easily accessible panels for attributes and elements to the right of the document editing area. You can double-click an attribute or element to insert it. Also includes an Insert menu.	Has easily accessible panels for attributes and elements to the right of the document editing area. You can double-click an attribute or element to insert it. Also includes a DITA > Insert sub-menu. The menu is not as full-featured as the one in XMetal. You have to rely more on the panels.
Metadata	Added using a dialog box.	Added using a pop-up list in the editing window.
Table Editing	Provides a simple dialog box for inserting table types: Normal, Properties, Simple, or Step Choice. Editing in the WYSIWYG view is as simple as table editing in MS Word. You can insert rows above and below, columns to the left and right, etc. The Table Properties dialog box enables you to fine-tune the format at the table, column, row, or cell level.	Provides a right-click menu to access table commands, as well as a toolbar. Table types are CALS or simple. Table editing is not as flexible or intuitive. For example, I could insert a row below another row but not above. I had to use the Text (raw tags) view to cut and paste a row above another row.
Images	Enables you to apply numerous properties before insertion: alt, description, dimensions, text wrapping, and alignment. A second properties tab in the dialog box provides additional choices such as revision and status (such as new or changed). When you insert a figure caption, XMetal inserts the fig tag and the necessary p tags.	Provides menu commands (main and right-click) for image insertion, but you have to add image properties afterward. The properties are available on the Attributes panel. Inserting a figure caption requires extra steps. You have to wrap the img tag with the fig tags and then add a p tag after the opening fig tag.
Links	Easy to insert. XMetal automatically assigns an ID to cross-references.	Easy to insert, though I had to manually assign IDs.
Change tracking	Simple to use. You can turn Track Changes on and off, make changes, and accept or reject them. Simple setup options are available in the Options dialog box. This feature is very similar to MS Word but simpler to use.	Very similar to XMetal's implementation. The main difference is that you can control option settings at the global level or project level.
