How to get documentation for element, attribute pattern?

[angelozerr]

I have implemnted successfuly the XML completion based on RelaxNG by using Pattern and visitor.

Now i would like to get the documentation for a given element, attribute and I noticed that ElementPattern doesn't store the annotation documentation.

It seems that https://github.com/relaxng/jing-trang/tree/master/mod/rng-schema/src/main/com/thaiopensource/relaxng/edit can parse and get the documentation of RelaxNG grammar, but it means that I need to parse twice the grammar:

• one to compute the grammar
• one to compute the documentation.

I tried to customize

jing-trang/mod/pattern/src/main/com/thaiopensource/relaxng/pattern/SchemaBuilderImpl.java

Line 766 in 84ec6ad

public ElementAnnotationBuilder<Locator, VoidValue, CommentListImpl>

but as SchemaBuilderImpl have a private constructore we cannot extend it.

Many thanks for you help.
