Maps to a UML Comment with or without the stereotype XSDannotation. The documentation content maps to the UML Comment body (name).

“documentation” maps as a UML comment, as outlined below:

• the “content” value - the comment name.

• the “xml:lang” value – the tag “xml:lang” value.

• the source value – the tag ”source” value.

“appinfo” maps as a tag value with the name “appInfoSource”:

• the “source” value will be the tag value.
• the “content” will be documentation for the tagged value.

When several annotation nodes appear on one element node, mapping shall be done as follows:

• the “documentation” text shall be merged into one UML comment with merged content, but the “content” and “xml:lang” tag values shall represent only the first matched values.

• “appInfo” shall have “content” merged into one tag “appInfoSource” comment, but the tag value shall represent the “appinfo” matched first.
