XML
A preference option has been added to make content assist more conscientious about grammar.
When this preference is enabled, suggestions that are 'strictly' grammatically valid will be shown first with bold icons. Other suggestions that
are applicable to this element scope but not grammatically valid will be shown below with a deemphasized icon.
To enable this feature go to the Preferences page as shown below and set the Suggestion strategy to "strict" (the default is "lax").
