$schema_name is the name of a supported schema. Currently only |
17
|
|

|
|
|
C is supported. $data is the data to be validated. $file |
18
|
|
|
|
|
|
is the absolute path to the file the data are coming from. $doc is the |
19
|
|
|
|
|
|
index of the document within $doc that is to be validated. The last |
20
|
|
|
|
|
|
two arguments are only there for better error reporting. |
