generate-id() inserts periods into name which limits usage
----------------------------------------------------------
Key: XALANC-445
URL: http://nagoya.apache.org/jira/browse/XALANC-445
Project: XalanC
Type: Bug
Components: XalanC
Versions: 1.6
Reporter: William D. seurer
"The generate-id function returns a string that uniquely identifies the node in
the argument node-set that is first in document order. The unique identifier
must consist of ASCII alphanumeric characters and must start with an alphabetic
character. Thus, the string is syntactically an XML name."
(from http://www.w3.org/TR/xslt#function-generate-id)
I have someone arguing with me that Xalan doesn't do this right because it
returns names like this "Nxxxxxxxx.yyyyyyyy" (where the x's and y's are hex
digits). The period in the middle is the sticking point. He says this is not
an ASCII alphanumeric character. For what he is doing with the names
(something with JavaScript) periods are not legal characters and he is stuck.
Unforunately there is no single clear definition of "ASCII alphanumeric
character" that I can find. Some of the definitions include all ASCII
characters in "alphanumeric" while others include only letters and numbers.
XML names are clearly defined and they can include periods (among several other
non-letter/non-number characters).
It can be argued that everything is working fine but it would probably be
better if some other character than a period was used in the middle there.
This specifically is for Xalan 1.6 but the code (in the getSuffix function of
FunctionGenerateID) is the same in Xalan 1.9 as well and probably other
versions.
