Comment (by jmr@…):

 * Please don't patch the Id line.
 * The revision should reset to 0 (the default) when the version increases.
 * Using an md5 checksum by itself should be considered deprecated. Using
 it in combination with another checksum type is OK if upstream publishes
 the md5. Looks like only a gpg signature is provided for xalan-c though,
 so after verifying the signature, you can just generate e.g. rmd160 and
 sha256 checksums to use in the portfile.
 * What's the problem with clang? We'd much prefer to fix problems
 compiling with clang instead of blacklisting it, since it is the default
 compiler on OS X and the alternatives are getting more and more outdated.
  * Please don't add trailing whitespace.
