dashes ('-') in custom tag names
Either I'm reading the spec wrong, or Jasper isn't treating these right.
In the JSP 1.1 spec
(ftp://ftp.java.sun.com/pub/jsp/11final-87721/jsp1_1-spec.pdf), Section
5.3.5 notes that the name element under the tag element has the following
model:
<!ELEMENT name (#PCDATA) >
#PCDATA ::= NMTOKEN
(The JSP 1.2 describes custom tag names essentially the same way.)
In the XML 1.0 specification, NMTOKEN (name token) is defined by the
following production:
[7] Nmtoken ::= (NameChar)+
[4] NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar |
Extender
but when I create a custom tag like <eg:foo-bar/>, then Tomcat generates
source code like:
_jspx_th_eg_foo-bar_0.setPageContext(pageContext);
which of course fails because '-' is not valid in a Java identifier.
(This is with "Tomcat Version 3.2 (final)", I haven't tried it 4.)
Assuming dashes are valid, the fix seems pretty trivial, but am I missing
something? Should dashes be valid in tag names? Colons (':')?
