JSP-style <?eval ${project.version}?> entity replacement also for attributes

[GoogleCodeExporter]

In the attached example file, the following expression 

  <para>Testing: <?eval ${project.version}?></para>

compiles and generates the expected output, e.g. for a version of 1.2.3 you get

  Testing: 1.2.3

However, the following expression

  <para>Testing: <ulink url="http://<?eval ${project.version}?>"/></para>

fails with

Error on line 11 column 108 of file:///C:/Users/.../src/docbkx/entity
-test.xml:
  Error reported by XML parser: The value of attribute "url" associated
with an element type "ulink" must not contain th
e '<' character.

Embedded error: org.xml.sax.SAXParseException: The value of attribute "url"
associated with an element type "ulink" must
 not contain the '<' character.

It would be nice if the entity replacement could also be applied to
attributes, as in this example. This is especially relevant for e.g. links
to API documentation which will frequently contain references to project
names and versions.

See the comments for http://code.google.com/p/docbkx-tools/issues/detail?id=48 
for a
possible workaround.

Maybe there is a simple solution, relying on maven resource filtering. The $ 
sign in ${prop} now needs to be escaped with its equivalent numerical $
