Yes.
For navigation purposes, ditac must ensure that some elements (i.e.
topics) are given unique IDs and this, no matter what the author has
specified in her/his DITA source file.
Therefore you'll find this function in PreProcessor.java:
---
protected static String setUniqueId(Element element, String id,
Map<String, Element> idToElement) {
String id2 = id;
int counter = 2;
Element e;
while ((e = idToElement.get(id2)) != null && e != element) {
if (counter >= 1000) {
break;
}
StringBuilder buffer = new StringBuilder(id);
buffer.append('-');
buffer.append(Integer.toString(counter++));
id2 = buffer.toString();
}
element.setAttributeNS(null, "id", id2);
idToElement.put(id2, element);
return id2;
}
---
Changing 1000 to 100000 is a quick and dirty fix for this problem.
Needless to say that we'll cleanly fix this bug in the next release of
ditac.
