Computed comment constructors
A computed comment constructor creates a comment node for which the content of the node is computed based on an enclosed expression.
The result of a computed comment constructor is a new comment node that has its own node identity.
Syntax
- comment
- A keyword that indicates that a comment node will be constructed.
- CommentContents
- An expression that generates the content of the comment. During processing, atomization is applied to the result of CommentContents, and each atomic value in the atomized sequence is cast to a string. The individual strings that result from the cast are concatenated with an intervening space character. If atomization results in an empty sequence, the sequence is replaced by a zero-length string. The content sequence cannot contain two adjacent hyphens or end with a hyphen.
Example
The following computed constructor
creates the comment <!--Houston, we have a problem.-->:
let $homebase := "Houston"
return comment {fn:concat($homebase, ", we have a problem.")}
