Modified: java/src/org/apache/xalan/xsltc/runtime Tag: XSLTC_DTM
AbstractTranslet.java
java/src/org/apache/xalan/xsltc/runtime/output Tag:
XSLTC_DTM StreamOutput.java
Log:
XSLTC_DTM performance work
Improvement in StreamOutput.escapeString(). Do not create the StringBuffer
if there is nothing to escape.
This change needs to be put back to the new serializer if it uses the same
code.
