p:compare — The standard p:compare step.
The p:compare step compares two documents for
equality.

Errors
| Code | Description |
|---|
err:XC0019 | It is a dynamic error (err:XC0019)
if the documents are not equal according to the specified comparison
method, and the value of the
fail-if-not-equal option is
true. |
err:XC0076 | It is a dynamic error (err:XC0076) if
the comparison method specified in p:compare
is not supported by the implementation. |
err:XC0077 | It is a dynamic error (err:XC0077) if
the media types of the documents supplied are incompatible with the
comparison method. |
Implementation defined features
- Implementations of
p:compare
must support the deep-equal method;
other supported methods are implementation-defined. - If
fail-if-not-equal is false, and the
documents differ, an implementation-defined
summary of the differences between the two documents may appear on the
differences port.
