Methods and apparatus are provided for assisting a user who is editing a markup document on a computer. The user is presented with the markup document on a display of the computer for editing and provided with grammatical assistance based on a grammar inferred from current content of the markup document. The grammar may be inferred and updated automatically after the markup document is loaded or edited. The assistance provided may be based on a combination of an inferred grammar and a real gramm...

The invention provides for the separation of formatting and content data in a first markup file (e.g., an HTML file) so that a second markup language file (e.g., an XML file) containing the content data and formatting or presentation data file (e.g., an XSL file) can be created. Content data in the first file that is to be converted is tagged. The tagged data may be included in an HTML file. The invention processes the tagged data so that content data is identified and used to generate a file in...

A soil resistant aqueous coating composition in which the binder consists of a blend of a low Tg polymeric dispersion and a high Tg polymeric dispersion. The PVC of the composition is less than the critical PVC and the Tg of the low Tg polymer dispersion is less than 0.degree. C. and the Tg of the high Tg polymer dispersion is a least 35.degree. C. and the volume ratio of low Tg polymer dispersion to high Tg polymer dispersion is from 0.4:1 to 1.4:1.

A method for making .beta.-ketophosphonates by reacting a trialkyl phosphonocarboxylate (such as triethyl phosphonoacetate) with an acyl halide (such as acetyl chloride) in a reaction involving ester formation, followed by decarboxylation, followed by purification. The reaction is run in a single solvent, which is not removed from the reaction mixture until the purification stage. Suitable solvents for this purpose include halogenated aromatic hydrocarbons (such as mono-chlorobenzene).

An extensible resource resolution framework. Executing code that references a resource invokes an interface of an extensible resource resolution framework. Parameters may be provided on the invocation to specify information pertaining to the current execution context. One or more resource resolvers are selected, transparently to the invoking code, as appropriate to a given situation (comprising, for example, the execution context). Preferably, the resource resolvers are contributed as plug-ins t...

A file validator technique for identifying a test specification to be used for testing validity of a file element associated with a file is provided. The test specification is a member in one of a set of test specifications embedded in the file validator and a set of test specifications not embedded in the file validator. According to the technique, a file element is selected, a pointer associated with the selected file element is selected, and a pointer is used to select the test specification ...

A method and system for specifying, in a schema mapping framework, a mapping between a source schema and a target schema. The source and target schemas are schemas included in respective groups of registered, heterogeneous schemas. The source and target schemas may be of different types. Serialized versions of the source and target schemas include source objects and target objects, respectively. A mapping model is serialized into mapping objects that include logical references representing the s...
